Abstract— In this paper, a transformer less dynamic voltage restorer (DVR) based on the multilevel inverter is proposed. This multilevel inverter uses reduced number of switches. As a result, the proposed DVR has lower number of switches in comparison with other multilevel inverter based DVR topologies. Also, it has lower loss and cost due to no need for injection transformers. The performance of the proposed model is simulated in MATLAB/Simulink environment.

 Index Terms— Voltage sags/swells, Dynamic Voltage Restorer (DVR), Asymmetrical multilevel inverter.
