A multi-port bidirectional converter includes a transformer, a primary full-bridge converter, first and second high-voltage power conversion units, first and second low-voltage power conversion units, a full-bridge diode rectifier, and a full-bridge inverter. The transformer comprises a magnetic core, a primary winding and five secondary windings. The primary full-bridge converter is coupled to the first primary winding and receives an input voltage. The first/second high-voltage power conversion unit is coupled to the first/second secondary winding and outputs the first/second high DC voltage to a first/second high-voltage battery. The first/second low-voltage power conversion unit is coupled to the third/fourth secondary windings and outputs the first/second low-voltage DC voltage to the first/second low-voltage battery. The full bridge diode rectifier is coupled to the fifth secondary winding. The full-bridge inverter outputs an AC output voltage.
