Users of power electronics devices employ technology to make their daily life easier and more efficient. In terms of affordability and effectiveness, the Dynamic Voltage Restorer is the greatest homemade power device for reducing voltage sag and swelling. The four major components of the DVR are the voltage source inverter (VSI), input transformers, filter, and DC energy source. They use the DVR principle of adding voltage in series with the main voltages to alleviate voltage disturbances. The Dynamic Voltage Restorer uses a variety of control mechanisms. This study introduces the discrete pulse width modulation (PWM) approach. PI controllers, mixed voltage and current controllers, and Fourier transforms are utilized to detect voltage sags and generate switching pulses for the dynamic voltage restorer's inverter. The recommended system was created using MATLAB, a computer program that controls itself via voltage reference signals. The findings indicate that a dynamic voltage restorer can improve voltage sag and rise in distribution networks.
