Investigation on single phase ac-ac dynamic voltage restorer towards mitigate voltage sag

Abstract

This paper presents an investi phase Dynamic Voltage Restorer (DV mitigate voltage sag. Single Phase M (SPMC) is presented as a direct AC replacing the Voltage Source Inverter (V DVR system. A simulation was Matlab/Simulink software to obser performance towards mitigating the volta to ground fault was used to create the d load and a Sinusoidal Pulse Width Mod strategy was used as the switching techniq SPMC switches.
