A Step-Up Switched-Capacitor Multilevel Inverter With Self-Voltage Balancing
IEEE Transactions on Industrial Electronics, 2014The objective of this paper is to propose a new inverter topology for a multilevel voltage output. This topology is designed based on a switched capacitor (SC) technique, and the number of output levels is determined by the number of SC cells. Only one dc voltage source is needed, and the problem of capacitor voltage balancing is avoided as well.

A Modular Multilevel Converter With Self Voltage Balancing
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019The modular feature of modular multilevel converter (MMC) distinguishes itself from other topologies for medium-/high-voltage applications. However, as the count of sub-modules increases, the control complexity of voltage balancing for each sub-module sharply increases.

Multilevel inverter with the ability of self-voltage balancing
IEE Proceedings - Electric Power Applications, 2006This paper proposes a new topology of multilevel inverter that can work in three operation modes: the single-direction-balance mode, the bidirection-balance mode and the nonbalance mode. Only a DC source is required in a single-phase new inverter that works in the single-direction-balance mode or the bidirection-balance mode.

A zigzag cascaded multilevel inverter topology with self voltage balancing
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008This paper presents a zigzag cascaded multilevel inverter topology. The proposed new inverter has the following advantages: 1) only one dc source is needed and with no voltage balancing problem, 2) the output voltage can be boosted or bucked, positive or negative, 3) input and output share the same ground.
