The quality of electricity is currently one of the main problems. This has become especially important with the introduction of sophisticated devices whose performance is very sensitive to power quality. A power quality problem is a phenomenon manifested as a non-standard voltage, current or frequency that results in a malfunction of the end device. One of the main issues addressed here is performance degradation. Custom power supplies are used to solve this problem. One such device is the Dynamic Voltage Restorer (DVR), which is the most effective and efficient modern self-powered device used in distribution networks. Its appeal includes lower cost, smaller size, and fast dynamic response to interference. This paper presents the modeling, simulation and analysis of a dynamic voltage restorer (DVR) using MATLAB. In order to improve the DVR's ability to recover from voltage drops, this paper deals with the modeling of the control structure using a discrete PWM pulse generator. The obtained results show that the developed DVR exhibits a good ability to starch the voltage level during voltage sag conditions.
