Seven-level boosting active neutral point clamped inverter using cross-connected switched capacitor cells

Abstract

In this study, an active neutral point clamped-type boosting switched-capacitor multilevel inverter (SCMLI) with selfvoltage balancing capability is proposed. In the proposed topology, a novel switched capacitor cell is used, which has eightswitches and two diodes. The presented topology has reduced power component count with self-boosting and balancingabilities. The distinctive features of the proposed topology are highlighted and benchmarked against other recent 7L-SCMLItopologies. To validate the feasibility of the proposed topology, experimental tests are performed on a 1 kW prototype hardwaresetup. © 2020 The Institution of Engineering and Technology.
