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
