Voltage Fluctuation Based Monitoring Scheme of Submodule Capacitors in Modular Multilevel Converter

Submodule (SM) capacitor is one of the critical components in modular multilevel converter (MMC) and will gradually age with the working time increasing, which brings potential challenges for the systems reliability. This article proposes a novel online capacitance monitoring scheme for SM capacitor...
