Zusammenfassung:A power control system includes a multi-phase power source, an ungrounded multi-phase load (14), a plurality of power switching circuits (12a-12c) and a plurality of zero-crossing circuits (16a-16c). The multi-phase power source includes a plurality of phase power outputs. The plurality of power switching circuits are each connected to provide power from one of the plurality of phase power outputs to the ungrounded multiphase load. The plurality of zero-crossing circuits are connected to provide control signals to the plurality of power switching circuits. Each of the plurality of zero-crossing circuits are connected between one of the plurality of power phase outputs and an ungrounded reference.
