Abstract
Summary
This paper proposes a new switched‐capacitor nine‐level (9L) inverter with reduced switch count. In the proposed topology, floating capacitor (FC) is employed as a voltage booster, and it does not need any additional sensors to maintain the voltage across the FC. Due to additional FC, the number of dc sources and voltage stress on switches is reduced. Moreover, the proposed topology can be cascaded to achieve more voltage levels. Various parameters are considered in the comparison of the proposed topology with other recent switched‐capacitor topologies. Simulation and experimental results demonstrate the performance with different load and modulation index variations.
