Application of three-level diode-clamped converter on 10kW distribution voltage restorer

Abstract This paper presents the application of three-level diode-clamped converter on 10 kW distribution voltage restorer (DVR) for creating compensation voltage. The three-level converter is designed by using IGBT as switching devices and is controlled by using MATLAB/Simulink through dSPACE board. The simulation results show the performance of DVR including the proposed converter and controller. The injection voltage waveform of three-level diode-clamped converter can be able to compensate the grid voltage in proposed time. Moreover, three-level diode- clamped converter can also get a higher voltage range. The experimental results show 10 kW DVR hardware implementation that can compensate the grid voltage with 0.1 second. Therefore, this study can be the prototype of DVR using three-level diode-clamped converter for future work.
