“…The comparison of the various MLI topologies is performed in terms of N S , N D , N T , the number of the capacitor ( N C ), the number of input DC sources ( N DC ), the peak inverse voltage (PIV), the total blocking voltage (TBV) and peak output voltage ( V LP ) of the circuits. The number of switches and gate drives for the proposed TMLI is less than the topologies in previous works 10,11,13,15,19,21,22 according to the output voltage levels, which clearly confirm the features of the proposed one. Furthermore, It is evident that the proposed TMLI has fewer transformers than the topology presented in previous studies 9–22 .…”

“…The impact of research efforts to minimize overall components has led to various interesting TMLI topologies as presented in previous works 9‐22 . The TMLI topology proposed in previous studies 10,11,15 reduces the input DC sources compared with conventional MLI and operates with low switching frequency giving improved efficiency. However, using many transformers in the MLI increases the cost and size of the MLI.…”

Summary A novel multilevel inverter (MLI) configuration with the hybrid switching technique is presented in this paper. The proposed MLI consists of the H‐bridge combination with unidirectional switches, half‐bridges, and transformers. The suggested MLI with the additional cascaded connection increases to higher voltage levels. The number of employed components in this topology is drastically minimized. Therefore, the complexity, cost, and volume of the proposed topology are also reduced. The operation of the suggested topology is tested through the improved novel switching technique. This modulation method reduces the total harmonic distortion (THD) and produces high root mean square (RMS) voltage. Further, a comprehensive comparison with the recent MLI topologies is performed to validate the merits of the suggested inverter. Simulation and experimental results verify the suggested topology performance using the new modulation technique at different loading conditions and modulation indices.
