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
