Abstract

The paper presents an accelerated simulation approach that allows analysis of power electronics circuits and more specifically the characteristics of their electronic switches. The approach allows improved simulation times for detailed analysis of voltages and currents during switching, while longer overall simulation time takes place ? analysis of different modes of operation for the specific circuit. The algorithm on which the suggested approach is developed is presented in details. It includes a pilot run for the complete simulation time using ideal switches, where based on a specified number of discrete values for inductor currents and capacitor voltages in the circuit a series of small time, precise step simulations with the real switches are made. Based on that series of simulation conclusion for the overall performance of the switches can be made. An example based on a boost converter is provided. Results from this example are given as a verification of the suggested approach.
