Abstract

Abstract: The algorithm of conventional space vector PWM for three-phase four-switch fault-tolerant APF chooses different coordinate transformation control algorithm based on the fault location selection of phase A, phase B, phase C. The calculation process involves a lot of coordinate operation, and, is not conducive to the fault switching. A unified SVPWM for three-phase four-switch Fault-tolerant active power filter based on inductor current is presented. The traditional SVPWM control needs complex coordinate transformations. The simplified algorithm takes the inductor current change as the control target, doesnot complicated coordinate transformation calculation, and the form of the calculation is unified, which is easy to the fault switching. At the same time, the calculation of three-phase four-switch active power filter is reduced effectively, and the harmonic compensation accuracy of the three-phase four-switch APF is improved. The simulation results verify the effectiveness of the proposed algorithm.
