MODULAR MULTILEVEL CONVERTER WITH HARMONICS COMPENSATION FOR STATE-FEEDBACK CONTROLLER

A.U. Lawan^*, A.Abdulkarim, I.S Madugu, A. B. Kunya, G.S. Shehu

The voltage variations among the sub-module (SM) capacitors result in harmonicssuperimposed unto the circulating current. The conventional control of the SM voltages usesa closed-loop proportional Integral (PI) controller based on carrier shifted pulse widthmodulation (CSPWM). The PI-controller provides a dc reference circulating current for thecon...

MODULAR MULTILEVEL CONVERTER WITH STATEFEEDBACK CONTROLLER FOR HARMONICS SUPPRESSION

A.U. Lawan^*, A.Abdulkarim, G.S. Shehu, A. Kunya, I.S Madugu

Control of submodule capacitor voltages and the circulating current within modularmultilevel converter (MMC) is essential to MMC performance. The circulating current hasan influence on the losses, rating of the power devices and voltage ripple. The circulatingcurrent tends to have csurrent harmonics due to the voltage disturbance on the submoduleca...
