Abstract

PECS (Power Electronics Circuit Simulator) enables the time-domain simulation of switched networks that may contain nonlinear elements. Focus has been placed not only on obtaining high speed, but also on achieving a very high degree of accuracy. A set of optimized computer algorithms that have been incorporated into PECS to achieve these objectives are explained. Examples run, which include a power-factor correction circuit containing a multiplier/divider element, have shown over an order of magnitude speed advantage over other leading approaches
