Multiple-port bidirectional converter

A multiple-port bidirectional converter, comprising:

• a transformer, a primary full-bridge converter, a first high voltage (HV) power converting unit, a second HV power converting unit, a first low voltage (LV) power converting unit, a second LV power converting unit, a full-bridge diode rectifier, and a full-bridge inverter;
• wherein the transformer comprises a core, a first primary winding, a first secondary winding, a second secondary winding, a third secondary winding, a fourth secondary winding, and a fifth secondary winding;
• wherein the primary full-bridge converter is coupled to the first primary winding and receives an input voltage from a primary direct current (DC) voltage source;
• wherein the first HV power converting unit, coupled to the first secondary winding, outputs a first high DC voltage to a first HV battery;
• wherein the second HV power converting unit, coupled to the second secondary winding, outputs a second high DC voltage to a second HV battery;
• wherein the first LV power converting unit, coupled to the third secondary winding, outputs a first low DC voltage to a first LV battery;
• wherein the second LV power converting unit, coupled to the fourth secondary winding, outputs a second low DC voltage to a second LV battery;
• wherein the full-bridge diode rectifier is coupled to the fifth secondary winding;
• wherein the full-bridge inverter is coupled to the full-bridge diode rectifier and outputs an alternating current (AC) output voltage to an AC load.
