In this, present a single-phase five-level inverter for high power applications. Whenever grid-connected system mainly focuses on maintaining less THD and less switching losses. The projected topology has a minimum number of switches as associated with existing topologies. In case, the inverter has a number of switches it produces high THD and switching loses similar more driving circuits are required. So in this proposed topology consider less number switches. Similarly, SPWM control technique is utilized to control the inverter. In SPWM techniques, level shifter modulation is implemented for proposed topology. With the help of Matlab software, the proposed topology is simulated and get results.
