Mitigation Of Voltage Sag With Transformerless Dvr Based On Reduced Switch Count Multilevel Inverter
Year: 2024
Type: article
Abstract: Voltage sag is widely regarded as one of the most critical power quality issues in power systems. Dynamic Voltage Restorers (DVRs) offer a costeffective solution to protect sensitive loads from such disturbances. Further reductions in cost, as well as improvements in reliability and efficiency, can be achieved by removing the injection transformer. This paper presents a transformer less DVR design based on a T-type multilevel inverter. Without an injection transformer, the proposed DVR is more economical, lighter, and more compact. The DVR controller uses d- q transformation, and MATLAB/SIMULINK is employed to generate the simulation results
