Pollution from consumers is the primary factor influencing power quality (PQ) in the distribution network. Preserve sensitive loads from voltage source imbalances, spikes, drops, and other potential hazards. It is imperative to possess a voltage regulator that can adjust to fluctuating circumstances. Rectifiers are connected in series to dynamically restore voltage. The charging of DVR storage is necessary due to voltage fluctuations. The utilization of multiple DVR converters enhances system harmonics. Synchronous reference frame control is implemented by distributed video recorders. This paper addresses the design and simulation of DVRs by employing a three-level inverter. Evaluate the performance of two- and three-level inverter DVRs in MATLAB. The output voltage THD is increased by a three-level inverter, while the reference number is preserved by a series voltage.
