Abstract
In this paper, a new topology is proposed for Z-Source Inverter (ZSI) based Dynamic Voltage Restorer (DVR) which is fed through a source side shunt rectifier. In the proposed system, the size of energy storage element is decreased in compare with the conventional systems where the rating of located power electronics devices is less than the systems using ZSI or boost choppers. The proposed system is able to compensate long and significantly large voltage sags and can acceptably reduce the downstream fault current. The proposed system is simulated in PSCAD/EMTDC and the results show the correct operation of the system.
