Abstract: A method and apparatus for generating a high voltage at a battery system. The apparatus in one embodiment includes a supply node configured for direct or indirect coupling to a supply voltage. A converter is coupled between an input node and an output node, wherein the converter is configured to operate in a forward mode or a reverse mode. The converter generates a voltage at the converter output node for charging a battery when operating in the forward mode, wherein a magnitude of the voltage generated at the converter output node is less than a magnitude of the supply voltage. The converter generates a voltage at the converter input node when operating in the reverse mode, wherein a magnitude of the voltage generated at the converter input node is different than a magnitude of a voltage provided by the battery. A control circuit is coupled to and configured to control operation of the converter in the forward mode or the reverse mode.
