ABSTRACT:
A system and method for providing harmonic currents to a harmonic generating load connected to a multiphase alternating current power system includes a zig-zag transformer and a current generator. The zig-zag transformer is electrically connected to the multiphase alternating current power system. The current generator is electrically connected between a neutral of the zig-zag transformer and a neutral return path of the multiphase alternating current power system. The current generator injects a harmonic current into the neutral of the zig-zag transformer which in turn, reduces the harmonic currents provided to the load from the multiphase alternating current power system.
