A new converter topology for advanced static VAr compensation in high power applications

Abstract

Two genetic configurations of forced commutated PWM (pulse-width-modulated) converters, i.e., voltage source inverters and current source inverters, have been proposed as advanced reactive power compensators. A new configuration combining the features of the two generic ones is proposed and analyzed in the present work. It is composed of a PWM current source inverter handling high power with very low switching frequency, and a PWM voltage source harmonic filter handling low power with a much higher switching frequency. The result is that switching losses and harmonic distortions are minimized simultaneously.<>
