This paper discusses a systematic method for deriving basic converter configurations that achieve power factor correction (PFC) and voltage regulation. The discussion begins with a general three-port representation of power supplies that provide PFC and voltage regulation. Based on this representation and a power flow consideration, a systematic procedure is derived to generate all possible minimal configurations. It is found that two basic converters are, in general, required for implementing any of the possible configurations. Among these configurations only a few have been known previously and been used in practice. The various possible configurations are compared in terms of their theoretical efficiency and control requirements of the basic constituent converters.
