ABSTRACT:
An inverter apparatus for a battery-powered vehicle drive which is selectively operable in either a normal drive mode or an alternative battery-charging mode. In the drive mode, the inverter functions to invert DC from the vehicle's on-board storage batteries to a polyphase AC to power the vehicle drive motor. In the battery-charging mode, the inverter draws charging current from an external energy supply source and supplies it to the battery as a DC charging current. The apparatus is usable with external energy supply sources varying widely in voltage and frequency.
