​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 Z-source 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.
