Abstract
Embodiments include a power processing system and methods of its operation in a plug-in electric vehicle. The power processing system includes at least one AC electric motor, a bi-directional inverter system, and an electronic control system. The electronic control system provides a drive function by providing first control signals to the bi-directional inverter system which, in response, draws DC electrical power from a DC energy source, converts the DC power to AC power, and provides the AC power to windings of the at least one AC electric motor. The electronic control system also provides a charging function by providing second control signals to the bi-directional inverter system which, in response, draws AC power from the windings of the at least one AC electric motor, converts the AC power to DC power, and provides the DC power to the DC energy source in order to recharge the DC energy source.
