Analysis and design of a 3-phase current source solid-state VAR compensator

A Reactive Power Condensation (RPC) system which employs a three phase current source foræ-conoomutated FWM rectifier is presented and analysed in this paper. Pulse width 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 selection of rectifier input and output filter components and closing of the loop around the reactive power æmmand signal. Finally, predicted results are verified experimentally.
