Abstract :
The principle of energy conservation is used to model pulse width modulation (PWM) DC-DC converters. A novel method of deriving circuit models of multiple switch and/or transformer PWM converters is introduced. The principle of energy conservation is used for including parasitic components in these models. Reflection rules are given which allow model simplifications. The circuit models can be used to derive large-signal and small-signal characteristics as well as to simulate the converter performance. As an example, a procedure of modeling the PWM push-pull converter is presented
