Abstract
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 to provide ground power to a parked aircraft, and a low voltage DC current on a battery charging power cable to charge batteries in nearby service vehicles. The power converter includes an AC to DC converter which converts the 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 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.
