Abstract: ABSTRACT This paper presents a novel high‐performance and dependable step‐up multi‐level inverter topology designed specifically for photovoltaic applications. A gain factor of nine is attained, coupled with automatic self‐voltage balancing of capacitors and the intrinsic capability to generate both positive and negative voltage levels. All power switches withstand voltages lower than the peak of the output voltage. The quantity of power switches, DC input sources, and the blocking voltage on the switches are reduced. Also, the proposed inverter demonstrates a minimal cost function in comparison to similar topologies. The performance of the 19‐level step‐up inverter has been confirmed through simulation as well as laboratory results obtained from a constructed prototype.
