A new seven‐level ANPC inverter structure with semiconductor device reduction

Abstract

AbstractAn active neutral point clamped‐type multilevel inverter (ANPC‐MLI) with self‐voltage balancing capability is being suggested for this study. A new switched capacitor cell with eight switches is used for seven‐level generation in the proposed topology. The topology proposed has decreased the power element count with the ability to self‐balancing of capacitor voltages and boosting ability. The distinguishing characteristics of the proposed topology are emphasized and compared with other recent 7L‐SCMLI topologies. Experimental testing on a prototype hardware is conducted to validate the feasibility of the proposed topology.
