Analysis and design of a three-phase current source solid-state VAR compensator

A reactive power compensation (RPC) system which uses a three-phase current-source force-commutated PWM (pulsewidth-modulated) rectifier is presented and analyzed. Pulsewidth modulation is also investigated as a means of reducing the size of reactive components. The proposed RPC system can compensate for leading and lagging displacement power factor. Other areas of investigation include the selection of rectifier input and output filter components and the closing of the loop around the reactive power command signal. finally, predicted results are verified experimentally.<
