Claim 0:
1. A split-phase bidirectional on-board charger (OBC) for use with a direct current (DC) voltage bus, the OBC having a charging mode and a discharging mode, comprising:
a switchgear block connectable to an offboard charging station during the charging mode, and to an external alternating current (AC) load during the discharging mode;
a first direct current-to-alternating current (DC-AC) converter;
a second DC-AC converter, wherein the first DC-AC converter and the second DC-AC converter are connected to the switchgear block; and
a DC-DC converter connected to the first DC-AC converter, the second DC-AC converter, and the DC bus, wherein during the charging mode the first DC-AC converter and the second DC-AC converter are configured to output a DC link voltage to the DC-DC converter, and the DC-DC converter is configured to output a DC charging voltage or current to the DC bus when the DC link voltage reaches a predetermined value, and wherein during the discharging mode, the first DC-AC converter and the second DC-AC converter are configured to receive a DC discharging voltage or current from the DC-DC converter and together selectively output a split-phase AC voltage through the switchgear block to power the AC electrical load.
