Abstract :
A three-phase solid-state voltage compensator system which employs a three-phase pulse-width-modulated (PWM) voltage-source inverter is presented and analyzed. This system can compensate for undervoltage, overvoltage and voltage unbalances produced by the AC mains. It also significantly improves the AC mains input power factor and substantially reduces any line-current harmonic generated by nonlinear loads. The paper discusses the proposed voltage compensator system in terms of principles of operation and power circuit design. The predicted results are verified experimentally.
