1. A vehicle comprising:
- an electric machine including two sets of galvanically isolated windings; and
a switching arrangement configured to,during propulsion, couple a first inverter with one of the sets and couple a second inverter with a traction battery while by-passing a power converter to permit power from the battery to flow through the sets, andduring charge, isolate the first inverter from the electric machine and couple the converter electrically between the battery and second inverter such that current from a charge port coupled with a source flows through the one and induces a voltage in the other of the sets for rectifying via the second inverter and boosting via the power converter to charge the battery while isolating the source from the battery.

Abstract
A vehicle includes an electric machine with two sets of galvanically isolated windings, and a controller. During charge, the controller isolates a first inverter from a first set of the two sets and couples a power converter electrically between a traction battery and second inverter such that charge current flows through the first set and induces a voltage in a second set of the two sets to charge the battery.
