Novel single‐armed modular multilevel converter for reducing total converter capacitance
IET Power Electronics, 2021 During normal operation of a conventional Modular Multilevel Converter (MMC), half of its capacitors remain bypassed at any time instant, increasing the total required capacitance for converter operation, and in turn leading to a larger size and volume ...

Modified grey wolf optimisation based reduced device count 17‐level hybrid multilevel inverter
IET Power Electronics, 2021 A 17‐level hybrid multilevel inverter (HMLI) using modified grey wolf optimisation (MGWO) is proposed here. The proposed HMLI requires only a single dc source and a lesser number of circuit elements to obtain a multilevel voltage level. The proposed HMLI
