THE UNIFIED SWITCHED INDUCTOR MODEL

Abstract

The Switched Inductor Model (SIM) is rigorously developed by considering the average voltages and currents in PWM converters. The limitations and error bounds of the SIM are examined and compared to those of the State Space Average model. The two model are found to be identical when the parasitic resistances are negligibly small. These errors are relatively small in practical converters. Good agreement was also found between computer simulations based on the proposed SIM and experimental results
