A Star-Channel Modular Multilevel Converter for Zero/Low Fundamental Frequency Operation without Injecting Common-Mode Voltage - 2017 PROJECT TITLE :A Star-Channel Modular Multilevel Converter for Zero/Low Fundamental Frequency Operation without Injecting Common-Mode Voltage - 2017ABSTRACT:This paper proposes a star-channel modular multilevel converter (MMC). It overcomes the zero/low-basic-frequency operation issues of standard MMC whereas not injecting the common-mode voltage (CMV). The proposed converter is characterised by the cross connections of higher three arms and lower 3 arms through two sets of star-channel branches. These star-channel branches rebalance the ability among 3 part legs, resulting in minimized submodule capacitor voltage ripples even at zero/low-fundamental-frequency operation without CMV injection. This feature enables the proposed converter to interface medium/high-voltage DC and variable-frequency AC systems. A 4160-V one-MW simulation model is performed in MATLAB/Simulink, and a 208-V five-kW experimental setup is made in the lab. Both of the simulation and experimental results verify the feasibility of the proposal. Did you like this research project? To get this research project Guidelines, Training and Code...
