| Abstract: | Capacitor voltage balancing is the premise for modular multi-level converter’s normal operation, which is a fundamental issue for all control algorithms. This paper describes the basic operating principles of modular multilevel converter and researches carrier phase shift in the modular multi-level application. To suppress the ca-pacitor voltage imbalance, the paper designs the capacitor voltage balancing controller, building a simulation mod-el in the MATLAB/Simulink. The results indicate that the designed controller can stabilize the capacitor voltage well. |
