  Mostly the power quality is affected due to the sensitive loads. These power quality issues create many disturbance like voltage sag, voltage swell, harmonic distortion and transient voltage. Due to the development of the power electronic technology, several mitigation techniques was emerged. From the wide range of mitigation technique we have taken a Dynamic Voltage Restorer (DVR) to protect from the sensitive loads. But it suffers with some of the drawbacks like, increased voltage limits, less capacity on compensating the line voltage and high transients. To overcome these drawbacks the DVR used in this research contains 3 ph six leg inverter and a LC filter to remove the unwanted frequencies. Moreover, a Space Vector Pulse Width Modulation (SVPWM) control strategy is used to manipulate the six leg power switched inverter, based on the space current and voltage converter switching. This research is intent for less expensive approach for this SRF theory helps to avoid the excessive controller in all three phases. Instead the d and q control strategy requires only two controller for all three phases. The performance analysis of the proposed system is evaluated by analyzing the power consumption and efficiency. Moreover the proposed system is compared with existing works related to this research work.
