In this study, a new topology for dynamic voltage restorer (DVR) has been proposed. The topology is inspired by the buck-boost ac/ac converter to produce the required compensation voltage. This topology is able to compensate different voltage disturbances such as sag, swell and flicker without leap of the phase angle. The mass of the proposed topology has been reduced due to lack of injection topology. In addition to, the required compensation energy is directly delivered from the grid through the grid voltage. Therefore, the massive dc-link capacitors are not required to implement. To verify the qualification of the topology, the simulation results by MATLAB/SIMULINK software have been presented. Moreover, an experimental prototype of the case study has been designed and tested.
