The overcurrent protection scheme is usually necessary to be built as part of the functions in power integrated circuits. The protection circuit requires to distinguish various fault conditions and to react differently based on the device safe operating area (SOA) limitation. At the same time, the circuit should also be relatively concise and suitable for integration. In this paper, a concise gate drive protection circuit is proposed to provide the complete function of overcurrent protection for LIGBT. The performance of the circuit was verified with experimental results. The implementation of the proposed circuit on lateral IGBT is also discussed and the simulation results are presented.","PeriodicalId":254764,"journal":{"name":"Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems.

LIMs are used in many industries as a transportation system. In a semiconductor factory, to produce dust during conveyance is not allowed. We developed the linear induction motor, used at such a factory. This system is AC induction type, and its secondary conductor completely levitates and moves above a stator by noncontact. In this paper, we propose a secondary conductor using the self-shading effect for stability levitation.

The new method uses a digital signal processor (DSP) controlled high switching frequency power electronic inverter to synthetically load the induction machine, while using a new real-time data acquisition system to accurately determine and record the machine's performance. The method proposed considerably reduces the testing time compared with conventional methods of efficiency measurement and the accuracy of the result is maintained. Moreover the use of the power electronic inverter allows a comprehensive control over all the quantities which determine the rate at which the power is dissipated inside the induction machine. This method can also directly quantify rotational losses of the induction motor under test.","PeriodicalId":254764,"journal":{"name":"Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems.

The method is based on an innovative iteration approach used to evaluate the AC terminal voltages of HVDC links at each integration step and is developed for enhancing the efficiency of stability trajectory calculations. In addition, the corrected energy function approach with corrected transient energy and corrected potential energy boundary surface is used in the AC/DC system for the estimation of transient energy margin. The approach provides more accurate results in transient stability assessment than conventional hybrid methods. Simulation results on a 36-bus, 8-generator test AC/DC power system are presented to show that the approach offers a promising tool to estimate transient stability limit conditions for AC/DC systems.","PeriodicalId":254764,"journal":{"name":"Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems.

Transformer leakage inductance and other parasitic inductance in the rectification loop are found to contribute to rectification loss. The body diode of synchronous rectifiers is on during current commutation in two SRs because reflected secondary voltage falls on these parasitic inductances instead of the gate terminal of SR in this duration. Body diode turn on greatly degrades the performance of SR. The case is worse in high frequency, high current applications. Detailed analysis of this phenomenon is given in the paper. An equivalent model is established to analyze and evaluate the performance of SR with the existence of parasitic inductance. Simulation and experiment waveforms confirm the model and analysis. Additionally, optimal driving waveforms for SRs are discussed. Two improved gate drive methods are presented and compared.","PeriodicalId":254764,"journal":{"name":"Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems.
