Abstract: Apparatus and method for determining a phase connection for a power conditioning unit (PCU). In one embodiment, the method comprises determining, by a controller coupled to a multi-phase AC line, a reference phase stamp; determining, by the PCU, a local phase stamp, wherein the PCU is coupled to a subset of phase lines in the multi-phase AC line; determining a difference between the reference phase stamp and the local phase stamp; comparing the difference to one or more of a first range of values or at least a second range of values; and determining the phase connection for the PCU based on whether the difference is within the first range or the at least a second range.

Abstract: Method and apparatus for converting DC input power to DC output power. In one embodiment, the apparatus comprises a plurality of flyback circuits, coupled in parallel, for providing DC-to-DC conversion; and a controller for automatically adjusting activation timing of each flyback circuit in said plurality of flyback circuits to achieve a balanced operation.
