Several benefits come with using SMC for DSTATCOMDC link voltage regulation, including a decrease in switching ripple in the DC side voltage and a steady DC side capacitor voltage under dynamic conditions. A DSTATCOM based CHBMLI supplying three phase loads is used to implement the SMC algorithm. When using the suggested dc link voltage balancing method, the DSTATCOM characteristics perform satisfactorily in terms of voltage balancing and the removal of power quality issues such current harmonics. Additionally, the DSTATCOM’s improved voltage balancing (IVB) scheme is used to compare the performance of the PI controller with the SMC’s improved voltage balancing method. The real-time investigation validates the performance characteristics, and the enhanced voltage balancing scheme of SMC results in better transient and steady state response.}, number={2}, journal={Majlesi Journal of Electrical Engineering}, publisher={OICC Press}, author={Chenchireddy, Kalagotla and Basha, Mulla Gouse and Kumar, Vislavath and Sydu, Shabbier Ahmed}, year={2024}, month={Jun.}, keywords={Power Quality, PI Control, Sliding mode controller (SMC), Cascaded H-Bridge multilevel inverter (CHBMLI)., Distribution static synchronous compensator} }
