   Analysis of Orthogonal Arc Suppression Coil and Compensation of Earth Faults
By Xiaoxia Wei, Yanchao Ji, Jianze Wang, Xianmin Mu [View]
[Download]

Abstract: This paper describes an orthogonal arcsuppression coil, which has wider adjustable range, less harmonic and easier control. Regulation of the coil inductance adopts dynamical orthogonal coil magnetic control, and the respond of control is fast and accurate. Working distance from the resonance point, the orthogonal coil monitors the capacitive current of power net, and immediately turns into full compensation state. When instantaneous earth fault occurs, the arc suppression coil compensates the fault arc automatically, while a permanent earth fault occurs, it can detects and trips the faulty immediately and using the thyristor switched capacitors to tune arc suppression coil sensitively. It also discuses dynamic arc suppression coil compensation system which is effective and correct.

   Driver Chip Design Considerations for VRM Applications
By Shih-hui Chen, Chung-Lung Pai, Dan Chen, Jing-meng Liu, Calvin Juang [View]
[Download]

Abstract: In this paper, a power loss model of VRMs will first be given. Actual power loss distribution on VRMs will be estimated for various VRM conditions. Comments will be made from the observations of the results and suggestions be made from the point of view of gate driver chip design. Discussion of future improvement possibilities is presented.

   Multidisciplinary Analysis of Electromechanical Actuator based on FEM – Circuit Simulator Coupling
By Jan Sitar, Pavol Bauer [View]
[Download]

Abstract: Design of an electromechanical system is multidisciplinary and so is its simulation. In this paper the three different types of co-simulation are compared and the output waveforms are presented. The co-simulation is realized between two different programs (power electronic circuit simulator – control part and finite element analysis – magnetic and mechanic model part). The simulations were realized for an electromechanical actuator fuel injection system. The output waveforms for coil current, forces, inductances and position are compared.
