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