ON-BOARD CHARGER CONTROL METHOD AND APPARATUS FOR MULTIPLE POWER SUPPLIES

Abstract: an embodiment control method for a bidirectional on-board charger (obc) includes measuring a first voltage of a first alternating current (ac) port connected to a first line among three-phase ac input lines and measuring a second voltage of a second ac port connected to a second line among the three-phase ac input lines and controlling a low-frequency leg among a plurality of legs in the bidirectional obc to be synchronized to the first ac port or the second ac port based on phase angles of the first voltage and the second voltage.
