Abstract
An electric three-phase power supply system includes a primary stage arranged to receive an input of three-phase alternating current power; a transformer stage arranged to receive power from the primary stage and to reduce the three-phase AC power in voltage level, the transformer stage include an independent secondary winding for each of the phases in the alternating current power; a power factor correction (PFC) stage having a plurality of PFC units that each receive AC power for one of the phases in the alternating current power from the transformer stage; and a pair of output terminals that receive power form the PFC units, wherein output terminals of each of the PFC units are tied to each other, and ground terminals of each of the PFC units are tied to a common ground.
