A bi-directional variable voltage converter transfers power between a traction battery and an electric machine inverter. The bi-directional variable voltage converter includes a capacitor, two power module phase legs, and an air-gapped transformer with three windings and no more than four terminals. A first of the windings defines a first terminal and a second terminal of the no more than four terminals. The first terminal is directly electrically connected with a positive terminal of the traction battery and the second terminal is directly electrically connected with a positive terminal of the capacitor and a junction between the second and third windings. A second of the windings defines a third terminal of the no more than four terminals directly electrically connected with one of the power module phase legs. A third of the windings defines a fourth terminal of the no more than four terminals directly electrically connected with the other of the power module phase legs.
