Modified grey wolf optimisation based reduced device count 17‐level hybrid multilevel inverter
IET Power Electronics, Volume 14, Issue 8, Page 1444-1456, 17 June 2021., 2021 Abstract 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 can also enhance the input voltage and has reverse current carrying capability.

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Selective harmonic elimination pulse‐width modulation (SHEPWM) is a widely adopted method to eliminate harmonics in multilevel inverters, yet solving harmonic amplitude equations is both time consuming and not accurate. This method is applied here for a 7‐level cascaded multilevel inverter (CMLI) with erroneous DC sources.
