Abstract/Summary This paper presents the medium voltage dynamic voltage restorer based on diode-clamped multilevel voltage source converter. This topology is well suited for high voltage and high power applications. The diode-clamped multilevel voltage source converter topology lies in the framework that DC-link capacitors common to three phases that can lower switching frequency. Small reactive filter component and easy implementation of modulation make this topology attractive. The proposed medium voltage dynamic voltage restorer, with high voltage power semiconductor modules and series booster transformer, is designed to protect sensitive loads at power distribution systems. A control technique based on voltage and current vector is also proposed for dynamic voltage restorer. Experimental results carried out by using computer program to validate the performance of the medium voltage dynamic voltage restorer model. Simulation results show the performance of the proposed medium voltage dynamic voltage restorer and prove the validity of the proposed topology. It is concluded that the proposed medium voltage dynamic voltage restorer works well both in balance and unbalance conditions of voltages.
