A dual function solid state power converter operable from a three phase AC input current simultaneously provides; an AC or DC output current on an aircraft power cable which extends from a stowed position to provide ground power to a parked aircraft, and a low voltage DC current on a battery charging power cable which extends from a stowed position to charge batteries in nearby service vehicles. The power converter includes an AC to DC converter which converts the AC input current to a DC current on an internal DC bus, a DC to AC converter which converts the DC bus current to an AC current at a higher voltage and frequency, or a DC to DC converter which converts the DC bus current to a lower voltage DC, for supplying ground power by means of a connecting cable to a parked aircraft, and a DC to DC converter for converting the DC bus current to a lower voltage battery charging current on the battery charging cable. In an airport environment the power converter may be advantageously mounted on a passenger boarding bridge and a motion inhibit circuit may be provided to prevent movement of the boarding bridge when either the aircraft ground power cable or battery charging cable are not in a stowed position. The power converter may also be mounted on a wheeled cart for positioning by a tug, or installed in a remote stationary position.
