Abstract
In one possible embodiment, a motor charging system for connection with a battery is provided having a rotor and a stator. The stator has delta H-bridge connected windings. The delta H-bridge includes an inverter at one side and a switching means at another side with each winding being connected between inverter pole switches and switching means pole switches. An A/C power port is connected to the windings such that when the switching means is off the A/C power port is connected to the battery bus via the windings and the inverter.
