Abstract :
A novel control method for shunt active power filters using SVPWM is presented. In the proposed control method, The APF reference voltage vector is generated to instead of the reference current, and the desired APF output voltage is generated by space vector modulation. The control algorithm is simple and can be realized by a low cost controller. The active power filter based on the proposed method can eliminate harmonics, compensate reactive power and balance load asymmetry. A 10 kVA laboratory prototype of APF is designed. This prototype adopts the voltage source inverter as the main power circuit and low cost DSP ADMC326 as control core. Simulation and experimental results proves the validity of the analysis and the feasibility of the APF with the proposed control method.
