In this study, an active neutral point clamped‐type boosting switched‐capacitor multilevel inverter (SCMLI) with self‐voltage balancing capability is proposed. In the proposed topology, a novel switched capacitor cell is used, which has eight switches and two diodes. The presented topology has reduced power component count with self‐boosting and balancing abilities. The distinctive features of the proposed topology are highlighted and benchmarked against other recent 7L‐SCMLI topologies. To validate the feasibility of the proposed topology, experimental tests are performed on a 1 kW prototype hardware setup.
