Abstract: This paper presents design and analysis of dynamic voltage restorer (DVR) employing five-level transistor clamped H-bridge (TCHB) inverter that increases the applicability of DVR to medium voltage networks. TCHB inverter is a newly developed topology of multilevel inverters (MLIs) which uses lesser number of components as compared to other topologies. Synchronous reference frame theory (SRFT)-based control algorithm is used for implementation of proposed DVR. The compensation capability of proposed DVR is tested for various voltage related power quality problems like sag, swell, harmonics, imbalance and their combinations through MATLAB/Simulink software and the simulation results are verified experimentally by using digital real-time simulator.
