Abstract:
1. A power system to provide power to a load, the power system comprising: a multiple-phase power transformation device to provide phase output voltages; a voltage reference generator to provide reference voltages usable to independently control corresponding ones of the phase output voltages provided by the power transformation device; a voltage control system, coupled to the voltage reference generator to receive the reference voltages therefrom and coupled to the power transformation device to receive sensed voltages representative of the phase output voltages decoupled from each other, to generate regulated voltages from the reference voltages and the sensed voltages; and a signal generation unit, coupled to the voltage control system to receive the regulated voltages and coupled to receive the reference voltages, to generate control signals based on the received regulated and reference voltages to control operation of the power transformation device to provide the phase output voltages.
