A Novel Fuzzy Repetitive Control Scheme Based Harmonic Suppression of Circulating Currents in Modular Multilevel Converters applications
G.Manikanteswara rao, SN.Meeravali
In a modular multilevel converter (MMC), the interaction between switching actions and fluctuating capacitor voltages of the sub modules results in second- and other even-order harmonics in the circulating currents. These harmonic currents will introduce extra power loss, increase current stress of power devices, and even cause instability during transients. Traditional methods for circulating current harmonic suppression have problems such as limited harmonic rejection capability, limited application area, and complex implementation. This thesis presents a plug-in repetitive control scheme with fuzzy logic controller is implemented to solve the problem. It combines the high dynamics of fuzzy controller and good steady-state harmonic suppression of the repetitive controller, and minimizes the interference between the two controllers. It is suitable for multiple harmonic suppression, easy to implement, and applicable for both single-phase and three phase MMCs. Simulation and experimental results on a single phase MMC inverter proved the validity of the proposed control method.
