摘要: High input power factor is becoming a mandatory requirement, in addition to tight output regulation, of DC supplies that derive directly from the AC mains. In principle, correction (PFC) and regulation functions are separately achieved by two stages. This paper addresses amalgamation stages form PFC voltage regulator. The focus noncascading structure allows higher overall efficiency be achieved. Unlike conventional cascade configuration, circuits discussed this allow part processed only one stage, thereby reducing amount redundantly constituent describes particular systematic synthesis method some important issues related control such converter circuits.
