Abstract
A power system for an automotive vehicle includes a matrix transformer having two separate cores, a primary winding wound around each of the cores, a first secondary winding wound around one of the cores, and a second secondary winding galvanically isolated from the first secondary winding and wound around the other of the cores. The power system also includes circuitry that transfers power from an AC source to the primary winding, transfers power from the first secondary winding to a traction battery, and transfers power from the second secondary winding to an auxiliary battery.
