An uninterrupted three-phase dynamic voltage restorer based on three-phase four-wire inverter is described in this paper. A rectifier is used to supply the inverter of DVR and makes DVR compensate sags continuously. The soft phase locked loop method is used to detect the source voltage and the inverter is controlled to solve the zero sequence voltage of power system by a new voltage space vector PWM algorithm that is different from the traditional method. Two foundational vectors of the SVPWM algorithm are used to produce the zero sequence voltage in this paper. The main circuit and the control algorithm were verified by simulation and experiment based on 6 kW DVR system using a split-capacitor PWM inverter.
