A new AC/DC rectifier using one power circuit for unity power factor and dual output application

This paper presents a new rectifier using one power circuit for dual output and unity power factor application. The proposed rectifier has structure with one power circuit combined boost and flyback converter and is simultaneously performed to PFC (power factor correction) and regular output voltage. Therefore, the proposed rectifier has better merits of low cost and small size than boost plus flyback rectifier using the two stage method and more exact control than the flyback with multi-winding rectifier. The operating principle of proposed rectifier circuit is illustrated. And to verify the validity of the proposed rectifier, simulation was performed.
