This paper presents a new DVR design and a control mechanism to minimize active power injection and forced the load voltage to be in phase with grid voltage during the sag, swell and short outage for the non linear load. The control technique incorporates a short time delay and mitigates the harmonic distortion during the charging of the energy storage capacitor. The new design is based on two continuous vector control. It extracts the fundamental components of the measured voltage and current using a 12 switch inverter connected in parallel to improve the time response. The proposed control method is tested on an 11 kV distribution system. Photovoltaic source with a boost converter is included to support the DC source during voltage sag. It shows that the proposed method improve the in-phase compensation technique, minimum active power and response for nonlinear loads.
