“…The PIV of this topology is high and it also requires two transformers to generate 19 voltage levels. However, the proposed HMLI requires lesser number switches to generate the same levels as compared to other selected HMLIs [26–29]. Topology [26] uses almost thrice the number of capacitors as compared to the proposed HMLI to obtain the same number of voltage levels.…”

“…The proposed topology possesses reverse current capability and is suitable for all power factor operations. The proposed HMLI is also compared with other reported HMLI topologies to exhibit its merits [25–29]. All these advantages cumulated in a single inverter make the proposed HMLI suitable for applications such as variable speed drives, active filters, and induction motor drives.…”

This paper presents a novel hybrid Multilevel Inverter (MLI) system. This hybrid system consisted of a nine-Level MLI unit that is connected back to back with a developed H-Bridge unit. The combination synthesizes only 10 power switches, two diodes, and four DC supplies to generate an output voltage waveform with 19 steps. The high number of steps in the output voltage helps produce a fine output waveform and more close to the sinusoidal shape with a small amount of THD. Also, it reduces the voltage stress across the switches and gives it a long lifetime, which brings more reliability. Moreover, the system synthesizes a reduced number of switches, which reduces the power losses and achieves high efficiency, and ensures small size and low cost for the proposed system. For amplifying the output power level, the paper presents two scenarios for the system expansion; both the scenarios achieve good

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.
