The ANPC-based multilevel inverters have been quite famous for over a decade due to their lower devices and high efficiency. However, as the number of levels increases, the ANPC topologies become unsuitable due to the increase in the component count and capacitor voltage balancing issue. This article proposes a novel ANPC nine-level topology with reduced components and voltage stress on the components. The proposed circuit has eight switches and one bidirectional switch, with two switched capacitors. The proposed topology has the voltage boosting ability with a maximum voltage gain of two times that of the conventional ANPC topologies. Further, the proposed topology does not need any voltage-balancing algorithm to maintain the SC voltages. The proposed topology is validated in hardware, and results are presented. The maximum voltage is 200 V, and the maximum current is 2.4 A with a maximum efficiency of 97% 100 W.
