Abstract
A multi-input power converter includes three bridge arm units connected between a three-phase AC power supply and a positive/negative DC bus. First and second capacitors are connected in series between the positive and negative DC buses with a node connected to a neutral point. Each bridge arm unit includes an inductor and a bidirectional switch unit connected in series with a node connected to a current direction control bridge arm between the positive and negative DC buses. Second ends of bidirectional switch units are connected to the neutral point. In a battery mode, two of the bridge arm units are as battery mounting bridge arms to constitute a DC loop with a rechargeable battery to supply power to the positive and negative DC buses, and the remaining bridge arm unit enables an inductor thereon to alternately connect the positive and negative DC buses to balance a bus capacitance voltage.
