PECS-Power Electronics Circuit Simulator

PECS (Power Electronics Circuit Simulator) enables the time-domain simulation of switched networks that may contain nonlinear elements. In the design of PECS focus has been placed not only in obtaining high speed but also in achieving a very high degree of accuracy. A set of optimized computer algorithms that have been incorporated into the software to achieve these objectives are explained. A closed-loop buck DC-to-DC regulator and a boost power factor correction circuit are simulated with PECS and a number of other simulators highlighting the speed and accuracy advantages of PECS.
