Abstract

The method of average modeling and simulation of pulsewidth modulation (PWM) converters is extended to include conduction losses. The method covers losses due to the inductor's resistance and due to the voltage drops across the switch and the diode. The method is demonstrated by considering an average model that is applicable to both current conduction mode (CCM) and discontinuous conduction mode (DCM) operations, and the switching from one to the other is automatic. The large-signal model is SPICE compatible and as such can be used to run dc (steady state), TRAN (large signal, time domain) and ac (small signal, frequency domain) analyses.
