Abstract
The requirement of an improved output waveform quality has increased the research in the area of multilevel inverters (MLIs). Active neutral point clamped (ANPC) MLI being one the popular MLI, this paper proposes a new hybrid ANPC topology for nine-level operation. It consists of ANPC leg, an H-bridge, and a floating capacitor (FC) fed H-bridge. The voltage across the FC is regulated using redundant switching states which does not involve complex computations. This balancing can be achieved irrespective of load power factor and modulation index. Extensive simulations are performed to verify the validity of the proposed topology and its control scheme. The corresponding results attesting its merits are presented. Finally, a comprehensive comparison with other classic and latest MLI topologies is presented.
