Summary The use of the dynamic voltage restorer (DVR) is preferred for the mitigation of voltage quality disturbances. In this paper, the real‐time application of a 5‐level transistor clamped H‐bridge inverter for the single‐phase DVR to realize the voltage sag mitigation is discussed. The controller is realized by comparing a sensitive load voltage with a reference voltage generated by the unit vector template method. MATLAB Simulink software is used to test the ability of the developed DVR by employing the in‐phase and pre‐sag compensation techniques. In addition, an experimental evaluation is performed in real time to observe the compensation capability of a 5‐level transistor clamped H‐bridge DVR. The design details of developed DVR are discussed, a prototype of DVR is also built in the laboratory. For verification of the capability of proposed DVR topology for voltage sag mitigation, experimental findings are presented.
