  • Bidirectional power converter having a charger and export modes of operation
    Patent number: 9584047
    Abstract: A bidirectional power converter that can be used in an electric vehicle to perform AC to DC power conversion to charge the electric vehicle's battery and to perform DC to AC power conversion to export power to run external electrical loads is described. The bidirectional power converter may include an AC interface coupled to a cyclo-inverter circuit, and a DC interface coupled to a H-bridge circuit. The cyclo-inverter can be electrically coupled to the H-bridge circuit through a transformer. The bidirectional power converter may include a neutral terminal on the AC interface that is coupled to the transformer through a filtering inductor.
