“…Several SC-based topologies have been suggested which possesses the boost/step-up ability [20][21][22][23]. In these configurations, the peak of the output voltage has higher values than the input supply voltage, whereas another suggested in [20,24] does not have. However, these topologies contain a higher number of switching devices to be operated in the output current paths, which results in lower efficiency.…”

A new switched-capacitor-based topology with features of boosting and self-voltage balancing of the capacitor has been proposed in this study. The proposed multilevel inverter topology uses two isolated dc voltage sources with a switchedcapacitor to produce 11 levels across the load. In this study, two different modes of the selection of dc voltage sources have been discussed for the proposed topology. Furthermore, the generalised structure of the proposed boost topology has also been discussed. Quantitative comparison with several topologies has been carried out to set the benchmark of the proposed topology. Selective harmonic elimination pulse width modulation technique has been adopted to improve the performance of the suggested topology. The power loss analysis of the proposed topology gives the maximum efficiency of 96.5% at the output power of 100 W and has an efficiency value of 95.3% at the output power of 500 W. The proposed topology has been simulated using PLECS and the simulation results have been verifying using an experimental prototype. The proposed topology has been tested for the different types of load and changes in the modulation index. The experimental results have verified the feasibility of the proposed topology.

Summary A 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.
