Power converter for vehicle charging

A power converter for a vehicle, the power converter comprising:

• a primary side having a line connection port and one or more primary alternating current (AC) to AC converters, wherein the line connection port further comprises:
• a first AC phase connection, a second AC phase connection, a third AC phase connection, a neutral AC connection, and a plurality of electrically controllable switches in electrical communication with the first AC phase connection, the second AC phase connection, the third AC phase connection, and the neutral AC connection;
• a secondary side having one or more secondary alternating current (AC) to direct current (DC) converters and one or more load connection ports, wherein at least one of the one or more load connection ports in electrical communication with a battery of the vehicle;
• and
• a transformer configured to transfer power between the primary side and the secondary side.

An on-board charging module (OBCM) for a vehicle, the OBCM comprising:

• a primary side having a line connection port and a plurality of bi-directional semiconductor switches, wherein the line connection port further comprises:
• a first AC phase connection, a second AC phase connection, a third AC phase connection, a neutral AC connection, and a plurality of electrically controllable switches in electrical communication with the first AC phase connection, the second AC phase connection, the third AC phase connection, and the neutral AC connection;
• wherein the plurality of bi-directional semiconductor switches includes one or more bi-directional switch pairs, and wherein the one or more bi-directional switch pairs further comprise:
• a first bi-directional switch pair having a first switch pair common node in electrical communication with the first AC phase connection;
• a second bi-directional switch pair having a second switch pair common node in electrical communication with the second AC phase connection;
• a third bi-directional switch pair having a third switch pair common node in electrical communication with the third AC phase connection;
• and
• a fourth bi-directional switch pair having a fourth switch pair common node in electrical communication with the neutral AC connection;
• a secondary side having one or more alternating current (AC) to direct current (DC) converters, one or more AC to AC converters, and one or more load connection ports, wherein at least one of the one or more load connection ports in electrical communication with a battery of the vehicle, wherein at least one of the one or more load connection ports is configured to provide a high-voltage DC output, wherein at least one of the one or more load connection ports is configured to provide a low-voltage DC output, and wherein at least one of the one or more load connection ports is configured to provide one or more AC outputs;
• and
• a transformer configured to transfer power between the primary side and the secondary side, wherein the transformer includes one or more magnetic cores, one or more primary windings, and one or more secondary windings, and wherein one of the one or more primary windings is in electrical communication with each of the one or more bi-directional switch pairs.
