-Abstract
The high power source which is included Electric-Double Layer Capacitors (EDLC) has been
configured to generate power higher than limited power. Rated voltage of EDLC has low maximum
value that's why it must need series-connection in high power applications. When EDLCs are
series-connected, each cell has an unbalance voltage by each tolerance. Unbalance phenomenon
is one of the facts reducing their life expectancy. Balancing or equalization is much studied in past
years, but it is mostly not for high power applications. Hence, charging-balancing circuit of seriesconnected EDLCs is designed to equalize each cell and module voltages in this paper. It is not only
discussion of circuit behavior but EDLC modeling of equivalent circuit which is considered parasitic
elements causing voltage unbalance. Proposed balancing circuit mitigates voltage unbalance of
EDLCs, as a result of charging-balancing circuit verified with simulation. Through the results, EDLC
could be utilized in high power applications such as pulsed power, prime power source, hybrid
electric vehicle. 2014 IEEE.

2.-Abstract MEEC models for RFIC design based on
coupled electric and magnetic circuits
This paper proposes the use of coupled electric and magnetic circuits in the schematic models of
high frequency integrated circuits, as an effective method to model the global inductive effects and
coupling. These pairs of coupled circuits, called magneto-electro-equivalent circuit (MEEC) models,
are obtained by partitioning the computational domain into several subdomains, each having its own
electromagnetic field regime. The model reduction method we propose can be used not only to
derive the full coupled electric and magnetic circuit model of a device starting from its layout, but
also to correct the electric schematic by adding inductive parasitic effects. The MEEC approach
uses special boundary conditions - called magnetic/electric hooks - on the interfaces between the
subparts in which the computational domain is partitioned. The success of the correct extraction of
inductive effects rely on the terminal reduction, i.e., the correct placement of magnetic hooks on the
interfaces. In order to find this placement, a heuristic approach based on IC layout analysis is
proposed. In order to consider the parasitic inductive couplings, the electric schematic circuit graph
is enhanced with geometric information from the layout (e.g., node coordinates). The MEEC-based
approach is validated for a real example of a low noise amplifier. Its initial layout design proved to
be wrong only after the fabrication and characterization of the first prototype. The use of the
inductive parasitic extraction tool, based on the MEEC approach, would have prevented this. MEEC
is an alternative approach to vector potential equivalent circuit, with respect to which advantages
and disadvantages are discussed. 1982-2012 IEEE.

vehicle based on intelligent circuit breaker of IPM modul
In order to meet the development trend of intelligent circuit breaker, the circuit breaker based on
L292 and IPM module and the bipolar H bridge motor drive control circuit for electric chassis vehicle
are developed. The principle diagram of control circuit of Motor H bipolar reversible PWM electric
chassis vehicle driving system is designed in this paper. Experiment results show that electrically
operated, working current monitoring and current limiting protection function are realized by this
control circuit, it can reduce the labour intensity of operators greatly and improve the stability of
control function. Through monitoring the motor current of electric chassis vehicle, the state of the
electric chassis vehicle can be obtained in real time and the reliability of medium voltage switchgear
can be increased. , 2015, Xi'an High Voltage Apparatus Research Institute

The electricity igniter testing circuit diagram and its work principle in the project are introduced, and
the circuit performance is tested under the high low temperature condition. In order to satisfy the
electric circuit testing needs in the great temperature range, the electric circuit threshold value is
adjusted by the actual value under the high low temperature condition, thus meeting the testing
requirements of the electricity igniters.
