A unified average model for single stage and two stage power factor correction converters

摘要

A unified average model for single stage and two stage power factor correction converters is given. Voltage control mode, peak current control mode and average current control mode can be simulated easily by changing parameters of the average model. With this model, simulation not only for small signal and static behavior but also for large signal and dynamic behavior of topologies mentioned above can be easily performed. It can be applied to simplify design process of the converters.
