Simulating switching power supplies presents many challenges. A variety of switch pole models is available, from the physics-based to the behavioral. The present work develops and demonstrates a behavioral model that works well in discontinuous mode. The new model eliminates the extremely fast time constants normally associated with switches in a high impedance state. Simulation time is improved and fixed-time-step algorithms are now stable with reasonable step size.
