A Cross Connected Asymmetrical Switched-Capacitor Multilevel Inverter [PDF]
IEEE Access, 2021 A Switched-Capacitor Multilevel Inverter (SCMLI) topology is proposed here, which can generate up to fifteen levels with one unit and can be extended further for getting higher levels. The proposed SCMLI has a lesser number of switching devices with respect to other recently proposed structures presented in this paper.
