Modular multilevel converter (MMC) (Lesnicar and Lesnicar in IEEE Bologna Power Tech Conf Proc 3:3–6, [1]) is one kind of converters suitable for high voltage occasion. However, when the number of sub-modules increases as the voltage level increases, the SVPWM for MMC becomes very complex. Though using m-mode SVPWM can simplify the modulation strategy, a lot of calculation time is still needed in practice (Tang et al. in IEEE Trans Power Systems 29:3030–3040, [2]; Ou et al. in IEEE J Emerg Sel Top Power Electron 2:1109–1116, [3]). Therefore, different from the previously proposed m-mode SVPWM strategies for inverters, this chapter first simplifies the topology of MMC sub-modules based on m-mode state controllability theory, thereby simplify the PWM strategy for MMC, which provides a new idea for the application of m-mode state controllability in the inverter.
