| Abstract |
This paper presents a shunt active power filter to compensate reactive power and reduce the unwanted harmonics. A shunt active filter is realized employing three-phase voltage source inverter (VSI) bridge with common DC bus capacitor. The shunt active filter acts as a current source, which is connected in parallel with a non-linear load and controlled to generate the required compensation currents. Two different proposed control methods for determiniong the reference compensating currents of the three-phase shunt active power filters based on proportional-integral (PI) controller and Artificial Neural Network (ANN) are presented. Current controller based on modified hysteresis current controller is used to generate the firing pulses. The proposed system is implemented using a high speed Digital Signal Porcessor (DSP). Experimental and simulation results are presented to confirm the validity of the proposed technique. |
