Abstract: This study proposes UPQC to enhance all Power Quality issues. The UPQC is outlined by consolidating a series APF and shunt APF. The adaptable FLC together with Series APF controls the voltage distortion. Shunt APF’s operation is controlled by d-q axes current from load current and DC-interface voltage is maintained through adaptable FLC. The stationary and transient action of controller circuit in various load current and variable voltage conditions is discussed. A versatile FLC is planned for the plant when its parameters are changing. The UPQC is used with static and switching nonlinear burdens. It can reduce voltage sag/swell, voltage variations and eliminates harmonics and so on. The proposed controller is implemented by using MATLAB.
