Abstract

Fast time-domain simulation of power electronic systems by using waveform-relaxation methods to reduce the simulation time is presented Algorithms for circuit partitioning, time windowing, and simulation scheduling are developed. Feasibility and advantages of applications are demonstrated by simulation results of a series resonant converter and a zero-voltage-transition PWM boost converter. The integration of waveform-relaxation techniques with averaging methods to further speed up transient simulations is also discussed.

基于波形松弛法的快速时域仿真
提出了利用波形松弛法缩短仿真时间的电力电子系统快速时域仿真方法,并提出了电路划分、时间窗和仿真调度等算法。通过串联谐振变换器和零电压转换PWM升压变换器的仿真结果,验证了该方法的可行性和应用优势。本文还讨论了波形松弛技术与平均方法的结合,以进一步加快瞬态模拟的速度。
