Single-stage bidirectional on-board charging module

An onboard charging module for a vehicle, comprising:

• a filter connected to a first conductor and a second conductor, wherein the first and second conductors are connected to a voltage source;
• an alternating current (AC)/AC converter including a first set of switches connected in series between the first conductor and the second conductor and a second set of switches connected in series between the first conductor and the second conductor;
• an isolation circuit including first terminals connected to a first node between the first set of switches and a second node between the second set of switches and second terminals connected to a third conductor and a fourth conductor;
• an AC/direct current (DC) converter connected to the third conductor and the fourth conductor;
• and
• a filter connected to the third conductor and the fourth conductor between the AC/DC converter and a battery,
• wherein each switch of the first set of switches and the second set of switches provides bidirectional current flow interruption and bipolar voltage blocking, and
• at least two switches of the first set of switches include connected source terminals and at least two switches of the second set of switches include connected source terminals.
