Zusammenfassung:This paper deals with the mitigation of voltage related PQ issues by using three phase neutral clamped VSI topology is used to realize the DVR and the design of DVR for the selection of suitable interface inductor, DC capacitor storage series resistance and the capacitance. Here three-phase four wire DVR with modified switching band controller topology is proposed, which overcome the frequent band violation, poor controllability and heavy filter currents, and compared to three-phase four wire DVR with conventional filter topology. The compensation capability of the proposed topology is analyzed based on simulation studies and corresponding results are compared with different switching control strategies. The consequent merits and demerits switching loss in VSI, ripple in compensated load voltages and error between reference injected voltages and actual injected voltages in different switching control strategies are discussed.
