| Abstract: | With the development of power electronic devices, the voltage source converter （VSC） is widely used in the field of HVDC transmission. Compared with the traditional twolevel or three-level VSC, modular multilevel converter （MMC） has the advantage of flexible voltage level control, less harmonic content and low switching loss. Thus, MMC receives extensive attention from research workers. This paper reviews the latest research from the working principle of MMC, modulation strategy and capacitor＇s voltage balancing strategy. Its applications are summarized, and the existing problems are discussed. |
