[Objectives] The Modular Multilevel Converter (MMC) has better speed regulation performance in AC transmission system because of its unique modularization and low switching frequency. In view of the problem of the capacitor voltage fluctuation of the sub-module and the overlarge common-mode voltage caused by the traditional high-frequency injection method in the marine medium-voltage ... https://www.roneverhart.com/Ray-Ban-RB3519-59mm/
