Abstract

This paper presents the application of dynamic voltage restorer (DVR) for the mitigation of voltage sags/ swells on power distribution systems connected to critical loads. DVR is a type of compensating custom power devices. The impedance source inverter employs a unique impedance network coupled with inverter main circuit and rectifier. By dynamically controlling the shoot-through duty cycle, the Zsource inverter system has the capacity to inject the boost or buck voltage required to compensate sags or surges. The proposed DVR topology is simulated using Matlab/Simulink and the experimental results are presented.
