Abstract: In renewable energy source applications, multilevel inverters with lower power components have become more popular in recent decades. This work exhibits a novel topology for high-quality output in PV applications, along with low-power switches and isolated dc sources. The core module of the suggested design may create a 13-level output waveform with two unequal voltage source values. The cascaded structure is intended to boost the voltage levels, and the related parameters are obtained analytically. The even and odd levels of voltage can be created natively without the usage of an additional H bridge circuit. Furthermore, the switches, gate driver circuits, dc sources, and standing voltage are fewer in number when compared to other recent topologies. Power losses and cost comparisons are calculated and given in monetary terms. This new research supports the idea that nearest level control (NLC) is used as a modulation scheme in the simulation modeling and experimental validation of the proposed topology.
