Abstract :
This paper describes how a piecewise linear circuit simulation model for the switching power MOSFET is used to understand and predict the switching losses in a two transistor forward converter and power factor corrected boost converter. Predicted losses are shown to correlate closely with the measured losses obtained from drain voltage and current waveforms
