It is shown that switching devices can be modeled as variable inductors which are controlled by independent off-on controllers. As the topology of the circuit changes due to closing and opening of the switches, it is shown that only one set of linear state-space equations is needed to characterize a power electronic circuit mathematically. Therefore, a system of converters with a large number of randomly variable-switched topologies can be simulated methodically. Based on this approach, the digital simulation of a resonant inverter is presented.
