FAULT CLEARING IN MIDPOINT GROUNDED SYSTEMS

A power supply system to provide power to a load connected between first and second connectors. The system includes a generator that produces an alternating current generator output and a rectifier that receives the alternating current generator output and converts it into a direct current output and provides the direct current (DC) output between the first and second connectors. The system also includes a filter connected to the rectifier and between the connectors and that smooths the DC output. The filter includes a midpoint configured to be connected to ground. The system also includes a fault clearing source connected to the first connector that provides a clearing voltage to the first connector when a ground fault occurs on the first connector.
