| Abstract: | It mainly introduced the topology and working principles of modular multilevel converter （MMC）, put forward a control strategy and sub-module storage capacitor pre-charge strategy of the MMC. In addition, the prototype of SVG was developed. The relevant experimental results show that the MMC has a good dynamic response performance, higher number of output voltage levels and small voltage harmonic content, which will contribute to the broad prospects of engineering application. |
