ABSTRACT
Motor control circuits are an effective way to reduce cost by using smaller
wire and reduced-amperage devices to control a motor. Many smaller motors use
the same size conductors for both control and power circuits, but as the
horsepower increases it becomes impractical to do so. Motor control circuits are
often connected to lower voltages than the motor they control to make it safer for
operators and maintenance personnel. A motor control circuit, for the most part,
is simply a switch (or group of switches) and a motor. If you keep the word
“switch” in mind, it helps keep the intimidating subject of “motor control” in its
proper context. For example, the following can be considered motor controls: A
time clock that operates a pool or sprinkler pump is nothing more than an
automatic switch. At a preset time, a set of contacts open or close (turn off or on)
Lists of Figures
Every power supply must obtain the energy it supplies to its load, as well
as any energy it consumes while performing that task, from an energy source.
Depending on its design, a power supply may obtain energy from various types
of energy sources, including electrical energy transmission systems, energy
storage devices such as a batteries and fuel cells, electromechanical systems
such as generators and alternators, solar power converters, or another power
supply.
All power supplies have a power input, which receives energy from the
energy source, and a power output that delivers energy to the load. In most
power supplies the power input and output consist of electrical connectors or
hardwired circuit connections, though some power supplies employ wireless
energy transfer in lieu of galvanic connections for the power input or output.
Some power supplies have other types of inputs and outputs as well, for
functions such as external monitoring and control.
Power supplies often have protection from short circuit or overload that
could damage the supply or cause a fire. Fuses and circuit breakers are two
commonly used mechanisms for overload protection.
Project Objectives
Conceptual Framework
An AC power supply typically takes the voltage from a wall outlet and
lowers it to the desired voltage. Some filtering may take place as well.
A power supply unit converts mains AC to low-voltage regulated DC
power for the internal components of a computer. Modern personal computers
universally use a switched-mode power supply. Some power supplies have a
manual selector for input voltage, while others automatically adapt to the supply
voltage.
Education sectors
The project aims to provide students, and even the educators, assistance
regarding the study of Electronics. They can see how it works well and also it
was detailed when it comes to designing a PCB.
For researchers
This project can be a reference for future researchers that will be dealing
with the same topic or to any kind of testing equipment of power supply and other
use of it.
Scope and Limitation
The project is intended to use for testing the efficacy of LM317 voltage
regulator in making a Variable DC power supply 0-12v. The project is limited to
the construction and demonstration of a variable DC. power supply and the
voltage range is from 0 to 12 volts.
Definition of Terms
Voltage Regulator – A device which maintains the direct current power supply
voltage for electronic equipment nearly constant of input alternating current line
voltage variations and output variations.
Capacitor -An electronic component that stores an electric charge and releases
it when required. A device for storing electrical energy, consisting of two
conductors in close proximity and insulated from each other.
CHAPTER II
Related Literature
There are two most familiar DC power supplies are used which are linear
power supply and switching power supply. Both the DC power supplies have
their own differences based on the characteristics. For linear power supply, it has
the preceding discussion points out two major shortcomings of a linear power
supply. It requires a low-frequency (60Hz) transformer. That means the size and
weight of the transformer are larger than high frequency transformer. Besides
that, the transistors in linear DC power supply operate in active region, incurring
a significant amount of power loss. It affected the overall efficiencies of linear
power supply usually in a range of 30-60%. 6 There is different with the switching
power supply. In this type of DC power supply, the switching elements such as
power transistors or MOSFETs operate as a switch: either completely off and
completely on. By avoiding the operation in active region, power loss of the
system is able to reduce. As a result, its efficiency between 70-90% ranges.
Since a high-frequency isolation transformer is used, the size and weight of
switching power supplies can be significantly reduced.

Testing the device would determine the goodness of the design in terms of
its structure stability, fitness to its applications, and quality of the design project.
Using livewire, the current and the voltages output can be seen. After
making the circuit, run it. And using a voltmeter, the output voltage cam be seen
if it meets the required adjustable 0 to +12V supply of power.

TECHNICAL STUDY
Base on the block diagram shown below you can know how each of the
components will interact with one another in order to work as a system. It also
shows how the single component flows to the others to make them work. In this
diagram we can easily see and understand if the project we made is working to
response the other device that will be supplied by our device.
Schematic Diagram
System Overview
Regulator (LM317t)
The LM317t has three pins: input, output and adjustment. The device is
conceptually an op amp with a relatively high output current capacity. The
inverting input of the amp is the adjustment pin, while the non-inverting
input is set by an internal bandgap voltage reference which produces a
stable reference voltage of 1.25V.
Transformer
is an electrical device that transfers electrical energy between two or more
circuits through electromagnetic induction.
Heat sink
is an electronic device that incorporates either a fan or a peltier device to
keep a hot component such as a processor cool.
Diode
1N5400 series is a similarly popular series for higher current applications,
up to 3 A.
Fuse
is a type of low resistance resistor that acts as a sacrificial device to
provide overcurrent protection, of either the load or source circuit.
Grommet
is a ring or edge strip inserted into a hole through thin material, typically a
sheet of textile fabric, sheet metal and or composite of carbon fiber, wood
or honeycomb. often made of metal, plastic, or rubber.
Switch
is an electrical component that can break an electrical circuit, interrupting
the current or diverting it from one conductor to another.
Printed circuit board (PCB)
Mechanically supports and electrically connects electronic components
using conductive tracks, pads and other features etched from copper
sheets laminated onto a non-conductive substrate.
Voltmeter
is an instrument used for measuring electrical potential difference
between two points in an electric circuit.
Resistor
is a passive two-terminal electrical component that implements electrical
resistance as a circuit element.
Wire
is a single, usually cylindrical, flexible strand or rod of metal.

Be knowledgeable of all electronic components. With this, doing an
electronic device will be easy to do. The function of each will be the determinant,
if this specific component will be used in a device. Also, knowing about the
device function will be a great addition to know what components to be used.

of each. Here are the different power supplies and there uses:
