ABSTRACT:
The present invention pertains to an AC electrical distribution system. The AC distribution system includes at least one nonlinear load. The nonlinear load causes distortion voltage in the AC distribution system. The AC distribution system also includes a zone filter which provides voltage to the AC distribution system. The AC distribution system can have a first zone which includes a nonlinear load and can have a second zone which includes at least one sensitive load. The zone filter regulates the voltage in the first zone as applied to the second zone and essentially eliminates the distortion voltage in the first zone as applied to the second zone. The zone filter can include a transformer device which provides a voltage to the AC distribution system. There is also a device for supplying power to the transformer device. Additionally, there is a sensor circuit for determining the distortion voltage and a fundamental voltage in the AC distribution system and providing a distortion and fundamental voltage correcting signal to the transformer device. The distortion and fundamental voltage correcting signal controls the transformer device such that the voltage in the first zone is regulated and voltage opposite to the distortion voltage is added to the first zone as applied to or subtracted from the second zone of the AC distribution system.
