Abstract
A power controller includes a plurality of power supply output circuits and a multi-level converter connected to the plurality of power supply output circuits to receive a plurality of sets of voltages. The multi-level converter is configured to supply power to a load from a plurality of output terminals. An observer module is operably coupled to the multi-level converter to selectively control multi-level converter common-mode voltage with respect to the plurality of power supply output terminals.
