General Description
The 0.2 kW Power Electronics Training Systems, Series 8032, are versatile and flexible training systems that
cover many topics essential to any power electronics program. Note that these training systems closely match
the Power Electronics Training System, Model 8010-A.
The 0.2 kW Power Electronics Training Systems use the same modular approach as the Electromechanical
(EMS) Training Systems, Series 8001 and 8006. The modular design allows experiments other than those
suggested in the courseware to be performed.
Although the modules in the training systems operate like industrial equipment, they are specially designed to
meet the particular needs of students. The equipment is easy to set up and operate. Because all important
circuit points are readily accessible through front-panel safety banana jacks, the interconnection between
modules is simple and straightforward. In all modules, special attention has been given to circuit protection,
thus making it possible to perform a great number of experiments with virtually no risk to the equipment.
Voltage and current isolators allow students to safely observe on an oscilloscope (available separately) the
high-level voltage and current waveforms found in power electronics circuits. The use of isolators allows the
voltages and currents to be handled without risk of electric shocks, short circuits, or equipment damage.
Conventional voltmeters, ammeters, power meters, a tachometer, and an electrodynamometer are provided for
the measurement of electrical and mechanical parameters in power electronics circuits.
The courseware consists of a nine-volume educational program, as well as an equipment familiarization guide.
The training program is divided into two separate sections: line-commutated and self-commutated converters,
which use, respectively, power thyristors (SCRs) and power IGBTs or power MOSFETs.
The volumes entitled Thyristor Circuits and PWM Circuits cover the fundamentals of line-commutated switches
(SCRs), self-commutated switches (IGBTs, MOSFETs, GTOs, etc) and the basic circuits in which they are used.
The volumes entitled Thyristor DC Motor Drives, PWM DC Motor Drives, Thyristor AC Motor Drives, and PWM AC
Motor Drives further expand on thyristor and PWM Chopper/Inverter circuits. Concepts and applications of
modern dc and ac motor drives are explored in each technology. Control loops for current, voltage, and speed
are implemented and experienced using analog PID regulation.
The volumes entitled AC Network Control Systems and HVDC Power Systems cover in detail power thyristors.
They deal with alternator voltage and speed regulation, as well as with high-voltage direct current transmission,
both topics being relevant to the field of electric power generation and transmission.
Finally, the volume entitled Industrial AC Motor Drives builds upon both the line-commutated switches and the
self-commutated switches to provide training in hybrid power electronics systems that use both types of
switches.

The equipment familiarization guide allows both instructors and students to become acquainted with the
operation of the 0.2 kW Power Electronics Training Systems.
As a highly modular, flexible, open-ended system, the 0.2 kW Power Electronics Training Systems lend
themselves well to a wide variety of sophisticated applications not covered in the courseware. As a result, the
equipment can also be used for comprehensive research work, allowing complex power electronics systems to
be set up easily and in a relatively short time. This enables the experimenter to focus on research work and
spend less time building such systems.
The conventional voltmeters, ammeters, power meters, oscilloscope, and electrodynamometer used in the 0.2
kW Power Electronics Training Systems can be replaced with the Data Acquisition and Control Interface, Model
Model 9063, and the Four-Quadrant Dynamometer/Power Supply, Model 8960-2. Both modules, when used in
conjunction with the LVDAC-EMS software, form a computer-based system for measuring, observing, analyzing,
and controlling electrical and mechanical parameters in electric power systems and power electronics circuits.
The LVDAC-EMS software is designed to run on a personal computer under the Microsoft® Windows® operating
environment.

Equipment Description
Mobile Workstation
8110-20
The Mobile Workstation is a ready-for-
use workstation that consists of two
fully assembled modules: a
Workstation, Model 8134-2, mounted
on a Mobile Storage Cabinet, Model
89117-1. Four rubber-tire swivel
casters allow easy movement of the
workstation in the laboratory
classroom. The lower portion of the
workstation serves as a storage
cabinet with two hinged panels and a
lock handle. Immediately above the
storage cabinet is a pullout work
surface with a scuff- and burn-
resistant laminate finish. The upper
portion of the workstation consists of
three rows of compartments designed
to house EMS modules. Two of these
rows have full-height compartments while the other row has half-height compartments. Each row of full-height
compartments can accommodate up to three full-size EMS modules or six half-size EMS modules, whereas the
row of half-height compartments can accommodate up to three half-size EMS modules.
Module Installation
The EMS modules are guided into position along stainless steel guide rails. Separators between each bay of the
workstation ensure perfect alignment of the EMS modules and allow their easy insertion in the workstation. A
holding mechanism ensures that each EMS module stays in place once it is installed in a compartment of the
workstation. Front-mounted push levers allow all EMS modules on a single row to be released for easy removal.
Safety Padlock Bars

Two safety padlock bars on the front of the workstation prevent students from removing EMS modules during
laboratory exercises. The bars can be removed and locked to the side of the workstation when the safety lock is
not necessary.
Additional Information
Six holes in the rear panel of the workstation allow connection to a power supply, as well as the connection of 2
kW machines to their interconnection modules. Assembly of the workstation before painting ensures that each
EMS module in the workstation is correctly grounded.

DC Motor/Generator
8211-05
The DC Motor/Generator is a dc
machine mounted in a full-size EMS
module. It can operate independently
as a dc motor or a dc generator. The
armature, shunt field, and series field
windings are terminated separately on
the faceplate to permit long and short
shunt as well as cumulatively and
differentially compounded motor and
generator connections. This machine
is fitted with exposed movable
brushes to allow students to study the
effect of armature reaction and
commutation while the machine is operating under load.
An independent, circuit-breaker protected, shunt-field rheostat is mounted on the faceplate for motor speed
control or generator output voltage adjustment. The speed of the DC Motor/Generator can be controlled using
the Thyristor Speed Controller, Model 9017, in both the open-loop and closed-loop modes of control.

Resistive Load
8311-05
The Resistive Load consists of a
module housing nine wire-wound
power resistors arranged in three
identical banks. Each bank consists of
three resistors connected in parallel
that can be switched on or off with
toggle switches to obtain various
resistance values. This allows the total
(equivalent) resistance of each bank to
be increased or decreased by steps.
Six safety banana jacks on the module front panel provide access to each resistor bank. The three resistor
banks can be connected separately for operation in three-phase circuits. Also, the three resistor banks can be
connected together for operation in single-phase circuits.
The Resistive Load is commonly used in conjunction with other basic load modules, like the Inductive Load and
the Capacitive Load to experiment with the effects of different types of load on a circuit.

consists of two chokes specially
designed to smooth current variations
occurring in thyristor (silicon-
controlled rectifier or SCR) circuits.
Each choke or inductor has two
separate identical windings,
terminated on the front panel by 4 mm
safety banana jacks. Internal electrical
components are identified on the
module front panel. The inductors can
be connected in series or parallel to show the effect of varying the inductance value on filtering. They can also
be used as inductive loads in dc and ac circuits.

Capacitive Load
8331-05
The Capacitive Load consists of a
module housing nine capacitors
arranged in three identical banks. Each
bank consists of three capacitors
connected in parallel that can be
switched on or off with toggle switches
to obtain various capacitance values.
This allows the equivalent capacitance
of each bank to be increased or
decreased by steps. Six safety banana
jacks on the module front panel provide access to each capacitor bank. The three capacitor banks can be
connected separately for operation in three-phase circuits. Also, the three capacitor banks can be connected
together for operation in single-phase circuits.
A permanently connected discharge resistor reduces the voltage across the terminals of each bank of capacitors
to 5% of the applied voltage within 25 seconds after the load is disconnected from the supply. The Capacitive
Load may be used with both dc and ac power.
The Capacitive Load is commonly used in conjunction with the other basic load modules, the Resistive Load and
the Inductive Load to experiment with the effects of different types of load on a circuit.

Fully Protected Transformer

8341-25
The Fully Protected Transformer is
fitted with three discrete windings.
Any winding can be used as either a
primary or a secondary, which
increases the number of laboratory
applications. Due to its numerous
taps, the Fully Protected Transformer
can be used with many different input
and output voltages. For this reason, it
can be used for impedance matching
and other transformer
experimentations. By using multiple Fully Protected Transformers, students can explore transformer phasing,
distribution transformers, open- and closed-delta transformer configurations, delta-wye, wye-delta, wye-wye,
and delta-delta connections. Other specialized transformer connections, such as Scott (three-phase to two-
phase), three-phase to six-phase, and zig-zag connections are also possible. Furthermore, resettable fuses are
used to protect the windings.
The Fully Protected Transformer is mounted in a half-size EMS module. The primaries and secondaries are
terminated on the module faceplate to 4 mm color-coded safety sockets and are identified by schematic
symbol, terminal number, voltage and current.

Tandem Rheostats
8737-05
The Tandem Rheostats comprises two
rheostats mounted on a common shaft
directly controlled by a single knob on
the module faceplate. This allows
simultaneous and equal variations in
resistance in both legs. Each rheostat
is protected from over-current
conditions by a thermal-magnetic
circuit breaker.
The main use of this module is in a
Ward Leonard system for speed
control of a DC Motor, Model 8211, whereby the speed and direction of rotation can be changed. In this
application the Tandem Rheostats are used to control the shunt field current of a dc generator, which in turn
drives a dc motor. However, since the rheostats are not interconnected, they can be used in applications where
one or two stand-alone rheostats are needed.

power most of the EMS modules of the
Electricity and New Energy Training
Equipment. This Power Supply
provides dc power and ac power, both
fixed and variable, single-phase and
three-phase. Color-coded safety
banana jacks provide access to all the
power sources in the Power Supply. All
these power sources can be used
simultaneously, provided that the total
current drawn does not exceed the

The Power Supply cannot supply all the amounts of current indicated by the current ratings on its front panel at
the same time. The current indicated for the fixed ac three-phase output section can only be obtained if no current
is drawn from any other section, because this section is protected by the main circuit breaker common to every
section. If currents flow in other sections, the available current for the fixed ac three-phase output section
*Note decreases. The variable ac output section and the variable dc output section are protected by a common set of
circuit breakers placed after the fixed ac three-phase output section, which means that the current capacity has to
be shared between the two sections. For instance, if current of the variable dc output section is at 70% of its
nominal value, current drawn from the variable ac output section should not exceed 30% of its nominal value. The
fixed dc output section is also protected by circuit breakers placed after the fixed ac three-phase output section.
IGBT Chopper/Inverter
8837-A5
The IGBT Chopper/Inverter consists of
seven insulated-gate bipolar
transistors (IGBT) mounted in a half-
size EMS module. Six IGBTs are used
to implement choppers and inverters.
These IGBTs are protected against a
variety of severe operating conditions,
such as short-circuits, overvoltage,
overcurrent, and overheat. The
seventh IGBT and a dumping resistor
allow smooth dissipation of excess
energy at the dc bus. The dumping circuit can be activated through the use of a toggle switch on the front panel.
The module switching control section allows 0/5 V pulse signals from either the Data Acquisition and Control
Interface, Model 9063, the Chopper/Inverter Control Unit, Model 9029, or any compatible 0/5 V control unit, to
be applied to the gating circuits of the IGBTs. The signals are input in the IGBT Chopper/Inverter module
through a 9 pin connector. Six miniature banana jacks are used as test points to monitor the pulse signals using
an oscilloscope. These jacks can also be used to inject 0/5 V pulse signals from an alternate control unit, as well
as to inhibit each gating circuit. The IGBT Chopper/Inverter module also includes a synchronization output to
trigger an oscilloscope when observing the switching control signals as well as a switching control disable input
that allows all six IGBTs in the chopper/inverter section to be switched off.
The IGBT Chopper/Inverter, Model 8837-A, is an earlier version of the IGBT Chopper/Inverter, Model 8837-B.

Electrodynamometer, Metric Units

8911-15
The Electrodynamometer is made of a squirrel-cage rotor fitted in a dc-excited stator. Mechanical loading is
achieved by increasing the stator field current, which generates eddy currents in the driven rotor. The stator is
trunnion-mounted on ball bearings and rotates against a helicoidal spring to oppose braking torque.
The Electrodynamometer can be coupled to a 0.2 kW drive motor through the use of the Timing Belt, Model
8942. The faceplate can be lowered to provide access to the inside for coupling the Electrodynamometer to the
drive motor. When closed, the faceplate is secured by two quick-lock fasteners.
The front-end bell is provided with a circular scale that indicates the torque developed. The circular scale is
graduated in Metric units (N⋅m). A damper lever is located underneath the dynamometer to prevent oscillation if
the power supply is applied while the dynamometer is turning. To measure the torque, this lever can be pushed
to adjust and read the torque. The Electrodynamometer is electrically powered from standard fixed ac line
supply.
A variant of the model expressing values in the U.S. customary system of units is also available (see Model
8911-0).

peripheral designed to be used in the
Electric Power Technology Training
Systems. Two operating modes are
available: Dynamometer and Power
Supply. A wide variety of user-
selectable functions is available in
each operating mode.
In the Dynamometer mode, the unit
becomes a four-quadrant
dynamometer that can act as either a
fully configurable brake (i.e., a mechanical load) or a fully configurable prime mover (i.e., a motor drive). In the
Power Supply mode, the unit becomes a four-quadrant power supply that can act as a dc voltage source, dc
current source, ac power source, etc.
In each operating mode, key parameters related to the selected function are displayed. Speed, torque,
mechanical power, and energy are displayed in the Dynamometer mode while voltage, current, electrical power,
and energy are displayed in the Power Supply mode. Optional functions, such as a small wind-turbine emulator,
a hydraulic turbine emulator, a solar panel emulator, battery chargers, an SDK (Software Development Kit) etc.,
can be added to the standard functions to further enhance the training possibilities of the Four-Quadrant
Dynamometer/Power Supply.
Two modes are available to control the function which the Four-Quadrant Dynamometer/Power Supply
performs: Manual and Computer-Based.
In the Manual control mode, the module operates as a stand-alone unit, and the function performed is selected,
set, and monitored using front-panel mounted controls and display. This mode provides access to all basic
functions. In the Computer-Based control mode, the function performed by the module is selected, set, and
monitored using the LVDAC-EMS software. In this mode, communication between the Four-Quadrant

Thyristor Firing Unit

9030-30
The Thyristor Firing Unit is a plug-in
control module designed for the
control of power thyristors in power
converter circuits. It generates four 0-5
V pulse signals in the single-phase
control mode, and six in the 3-phase
mode. These control or “firing” signals
are brought out to a 9-pin socket and
can be routed to the Power Thyristors,
Model 8841, through the use of an
included mating 9-pin socket. The
firing angle is determined by a low-
level dc signal applied at the angle
control input. The dc source output on
the front panel can be used to produce
this control signal. Four conversion
functions can be selected to change the direction, and the rate of change of the firing angle which can be easily
monitored on a 7-segment display on the front panel. A synchronization signal from the ac network is applied at
safety 4 mm sockets.

The P.I.D. Controller is designed to be
used as a core unit in the
implementation of control systems
containing analog feedback loops. It
contains a P.I.D. (Proportional,
integral, Derivative) amplifiers section
which is used to condition the analog
control signal with proportional,
integral and derivative effect. The gain
of each of these amplifiers can be varied independently to control these effects.
The other sections include circuit elements to achieve feedback signal amplification, signal rectification, low-
pass filtering, error detection and output signal summation and limiting. The limiting section includes an “Anti-
Reset” circuit which prevents the integrating amplifier in the P.I.D. Amplifier’s section from saturating. All these
elements can easily be interconnected through the use of miniature 2 mm banana plug connection leads.

Current/Voltage Isolator
9056-15
The Current/Voltage Isolator converts
a high-level current and a high-level
voltage (ac or dc) into two low-level (0
to ±10 V) output signals, electrically
isolated from the high-level signal
source. This allows observation of the
signal waveforms in power circuits
using a conventional oscilloscope. The
output signals can also be used in
control circuits as current or voltage
feedback signals.
The isolated signal at the current
output (I) is proportional to the input
current. Similarly, the isolated signal
at the voltage output (E) is
proportional to the input voltage. Both
isolators can be used simultaneously. Model 9056-1 is designed to be used with 0.2 kW EMS systems, while
Model 9056-A is designed to be used with 2 kW EMS systems.
The Current/Voltage Isolator is a plug-in module designed to be inserted into the Enclosure / Power Supply,

used to implement choppers and
inverters. These IGBTs are protected
against a variety of abnormal
operating conditions, such as short-
circuits, overvoltage, overcurrent, and
overheat. The seventh IGBT and a dumping resistor allow smooth dissipation of excess energy at the dc bus.
The dumping circuit can be activated through the use of a toggle switch on the front panel.
The module switching control section allows 0/5 V pulse signals from either the Data Acquisition and Control
Interface, Model 9063, the Chopper/Inverter Control Unit, Model 9029, or any compatible 0/5 V control unit, to
be applied to the gating circuits of the IGBTs. The signals are input in the IGBT Chopper/Inverter module
through a nine-pin connector.
Six miniature banana jacks can be used as test points to monitor the pulse signals using an oscilloscope. These
jacks can also be used to inject 0/5 V pulse signals from an alternate control unit, as well as to inhibit each
gating circuit. The IGBT Chopper/Inverter module also includes a synchronization output to trigger an
oscilloscope when observing the switching control signals, as well as a switching control disable input that
allows all six IGBTs in the chopper/inverter section to be switched off.

peripheral designed to be used in the
Electric Power Technology Training
Systems. Two operating modes are
available: Dynamometer and Power
Supply. A wide variety of user-
selectable functions is available in
each operating mode.
In the Dynamometer mode, the unit
becomes a four-quadrant
dynamometer that can act as either a
fully configurable brake (i.e., a mechanical load) or a fully configurable prime mover (i.e., a motor drive). In the
Power Supply mode, the unit becomes a four-quadrant power supply that can act as a dc voltage source, dc
current source, ac power source, etc.
In each operating mode, key parameters related to the selected function are displayed. Speed, torque,
mechanical power, and energy are displayed in the Dynamometer mode while voltage, current, electrical power,
and energy are displayed in the Power Supply mode. Optional functions, such as a small wind-turbine emulator,
a hydraulic turbine emulator, a solar panel emulator, battery chargers, an SDK (Software Development Kit) etc.,
can be added to the standard functions to further enhance the training possibilities of the Four-Quadrant
Dynamometer/Power Supply.
Two modes are available to control the function which the Four-Quadrant Dynamometer/Power Supply
performs: Manual and Computer-Based.
In the Manual control mode, the module operates as a stand-alone unit, and the function performed is selected,
set, and monitored using front-panel mounted controls and display. This mode provides access to all basic
functions. In the Computer-Based control mode, the function performed by the module is selected, set, and
monitored using the LVDAC-EMS software. In this mode, communication between the Four-Quadrant
Dynamometer/Power Supply and the host computer running the LVDAC-EMS software is achieved through a
USB connection. This mode provides access to all basic functions, as well as to additional advanced functions.
