Designing SMC Boost Converter for DVR Using VSI to Mitigate Voltage Disturbances And Harmonics

In this paper a new topology for dynamic voltage restorer is designed at the load end to maintain voltage tolerance and mitigate total harmonic distortion (THD) which meets IEEE-519 and IEEE-1159 specifications. This proposed architecture consists of dynamic voltage restorer (DVR), including loadable batteries, switches, SMC boost converter and an injection transformer. The simulation results obtained using MATLAB/Simulink demonstrate that the total harmonic distortion is significantly.
