The power quality has become one of the most significant problems for power electronics. Unified power quality conditioner is one of the power electronics devices used for improving the power quality problems. During this problem the current across the DC-link is varied from the rated value. DC-link current regulator is used to derive the actual reference signal from the distorted signal. In this paper, Genetic Algorithm (GA) optimized neural network is used to regulate the DC-link current and for current control of the active shunt filter instead of conventional controllers.
