Abstract
Control of an AC-to-DC power supply assembly fed by a three-phase AC source is provided by: determining whether the power supply assembly includes greater than three single-phase power regulators feeding a common load, with multiple regulators being connected in parallel across a common phase of the AC source, and if so, summing currents provided by the regulators to the common load; and ascertaining whether the summed current is less than a predefined threshold, and if yes, operating the power supply assembly in a line balance mode to maintain power drawn on the phases of the AC source in balance, and if greater than the predefined threshold, operating the power supply assembly in a maximize power mode wherein power is provided to the common load without maintaining power drawn on the phases of the AC source in balance.
