Low Frequency Modular Multilevel Converter Topology for Improved Dynamic Performance of Variable-Speed AC Drives

Abstract

This venture shows a control conspire for the particular multilevel converter (MMC) to drive a variable-speed air conditioning machine, particularly concentrating on enhancing dynamic execution. Hypothetically, the vitality adjust in the MMC cell capacitors is inclined to be unsteady at start-up and lowrecurrence operations. Also, the MMC topology basically requires propelled control methodologies to adjust vitality and stifle the voltage throb of every phone capacitor. This venture proposes a control methodology for the powerful unique reaction of MMC even at zero yield recurrence utilizing leg balance voltage infusion. The leg counterbalance voltage for adjusting the arm vitality is delivered by direct figuring without the coursing current control circle controller. On account of the exceedingly unique leg balance voltage from direct computation and not traditional circling current controller, the dynamic execution of a MMC at low speeds has obviously made strides. The air conditioner machine has been driven from halt to evaluated speed without exorbitant cell capacitor voltage swells using this proposed technique. The reproduction comes about check that steady operation is ensured down to <2% of the evaluated speed under 40% stage stack torque unsettling influence. The size of converter yield voltages are expanded, utilizing fuzzy controller. The outcomes were broke down in MATLAB/SIMULINK condition.
