Hybrid active Power filter for power conditioning by using Space Vector Modulation controller

Active power filters are widely used in power systems due to their advantages to maintain power quality. In this paper, presents a control method for hybrid active power filter using Space Vector Pulse Width Modulation (SVPWM). In the proposed control method, the Active Power Filter (APF) reference voltage vector is generated instead of the reference current, and the desired APF output voltage is generated by SVPWM. Proper controller is developed to maintain power quality with APF. The entire power system block set model of the proposed scheme has been developed in MATLAB environment. The APF based on the proposed method can eliminate harmonics, compensate reactive power and balance load asymmetry. Extensive simulation results are presented with case studies
