Abstract

Average modeling of PWM converters is reexamined in the light of the behavioral dependent sources now included in modern versions of electronic circuit simulators. A topology independent behavioral model is developed to emulate the operation of PWM converters in voltage and current modes, for continuous and discontinuous inductor current cases. It is shown that, in general, the operation of the switching part involves three behavioral blocks: the Generic Switched Inductor Model (GSIM), the Duty Cycle Generator (DCG) and the Inductor Current Generator (ICG). Explicit expressions and equivalent circuits are developed for all possible modes of operation.
