This paper discusses a control method of a three-phase four-wire instantaneous-reactive-power compensator. This method is based on a balanced time-variant conductance circuit model. The compensator controls the line currents so as to equate instantaneously the currents of the conductance model. The zero-sequence current of the line can be eliminated without using an energy storage component in the compensator. This control strategy is verified by simulation study.
