Three Level Four Leg Shunt Active Power Filter Based a New Three Dimensional Space Vector Modulation strategy in the αβ0-axes

Abstract

This paper presents a new Three level Three Dimensional Space Vector Modulation (Three level 3D-SVM) strategy for three level four leg Neutral Point Clamped (NPC) inverter controlling which is competent to operate in Shunt Active Power Filter (SAPF), in order to reducing the source harmonic currents and the inverter harmonic output voltages, eliminating the zero-sequence current caused by single-phase non-linear loads, reducing the switching frequency and voltage supported by the switches, and to compensate the reactive power. Simulation results of three level four leg Shunt Active Power Filter performances are presented to validate the proposed three level 3D-SVM strategy for switching signals generating
