“…A fivelevel CHBMLI has been developed for wind mill applications, in which both simulation and experimental results have been compared. The limitation of this paper is that the output voltage levels are less and the switching device required is higher than the other topologies (Palanivel et al, 2018). Threephase modified nine-level inverter topologies consisting of eight switches per phase totally 24 switches has been reported for PV applications and simulation and experimental results have been compared.…”

Purpose Multilevel inverter (MLI) is a prevailing sensible alternative to two-level inverters that offer a high-quality output voltage waveform, wherein the multiple input direct current (DC) levels are established by using isolated DC sources, batteries and renewable energy sources. The purpose of this paper is to develop MLI to offer lower total harmonic distortion (THD), higher output voltage levels and reduced switching components for high power applications. Design/methodology/approach In this paper, a new tapped sources stack succored modified HX bridge MLI (TSSSMHXBMLI) topology is proposed which includes two modules, such as tapped sources stack (TSS) and modified HX bridge inverter, which perform their function in a single stage. Also, this paper outlines the formulaic implementation of the multicarrier/sub-harmonic pulse width modulation (MCPWM/SHPWM) in a Xilinx Spartan3E-500 field programmable gate array (FPGA) is suitable for the developed MLI. Findings The feasibility of the suggested topology is well proved by both simulation and experiment results. Practical implications This paper examines a new topology of TSSSMHXBMLI with a view to minimize total count of switching components against basic MLI topologies. The operating sequence of the suggested TSSSMHXBMLI topology is verified with the simulation study followed by an experimental investigation. Originality/value The simulation and experimental results of suggested MLI topology reveals to obtain lower THD, higher output voltage levels and reduced switching components for high power applications.
