Shiva Naik, B.Yellasiri, Y.Venkataramanaiah, J.2026-02-052020International Journal of Circuit Theory and Applications, 2020, 48, 3, pp. 420-434989886https://doi.org/10.1002/cta.2748https://idr.nitk.ac.in/handle/123456789/24021A new nine-level natural-balanced boost hybrid multilevel inverter (BH-MLI) is proposed in this paper. Each phase of the proposed BH-MLI is designed with only 11 semiconductor switches and two electrolytic capacitors. Here, the capacitor voltages are balanced by utilizing the series-parallel and natural balancing techniques effectively. Furthermore, the proposed circuit eradicates the multiple DC sources by introducing a single DC link for single- and three-phase applications. The proposed topology can be easily extendible to obtain higher level output voltage waveform due to its modular-switched capacitor cells (SCCs). Besides, the higher voltage level generation does not pose high-voltage stress on any of the topology components, as the blocking voltage of all devices within the source voltage magnitude. Further, a quantitative comparison is conducted among the state-of-art switched-capacitor multilevel inverter (SC-MLIs) to highlight the superiority of the proposed configuration. Finally, the performance of the proposed BH-MLI is experimentally validated with phase disposition-pulse width modulation (PD-PWM) and round control method at different modulation indices, load conditions. © 2020 John Wiley & Sons, Ltd.Electrolytic capacitorsHVDC power transmissionPulse width modulationTopologyVoltage controlboost gainExperimental verificationHybrid multilevel inverterMultilevel inverterQuantitative comparisonSingle stageSwitched capacitorSwitched capacitor cellsElectric inverters
