Abstract: The objective of this study is to present the development of a dynamic voltage restorer (DVR) which employs a cascaded H-bridge multilevel inverter. DVR is a power electronic converter based on custom power device used to compensate for voltage variations. DVR does not need active energy storage systems like batteries as the zero energy compensation method is used. The control system may lead to challenges as compared with other DVR systems. To overcome this challenge a control method is used. In addition to minimize the delay of DVR and to mitigate the voltage sags, a three phase estimation method is used. The estimation method and control scheme is performed by using MATLAB/SIMULINK.
