Raising environmental concerns raised the usage of renewable energy sources. Inverter being main part of energy conversion system converts DC current produced from renewable source like solar PV cell to AC current used by load centers. Development of topologies that work efficiently when sourced with dynamically varying input is in high demand in the market. This paper deals with one of the newly developed reduced switch topology that provides flexibility of producing higher voltage levels while decreasing requirement of separate DC sources. Presently, though many of reduced switch topologies developed, least number of them ensures their flexibility and efficient working with real-time applications such as solar, wind, and industrial applications. Thus, in this paper, steady-state and transient analysis of newly developed rung ladder-structured multilevel inverter is studied with PV as source, and working of topology under real-time scenario is analyzed. A simple modulation technique is proposed for topology to trigger the switches. The analysis is explored in Simulink MATLAB 2018a, and results are discussed.
