Modeling and control of single-stage voltage-source and current-source PFC converters

摘要

Simple and accurate average quasistatic models for single-stage voltage-source and current-source PFC converters are presented. Based on small-signal analysis of the models, authors found the transfer functions of voltage and current loops for both types of converters operating in different line conditions. This study is useful for designing fast compensators for single-stage CCM PFC converters.
