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.

Summary Multilevel inverters are very popular in renewable energy applications. These inverters produce output voltages close to sinusoidal and have lower harmonics as compared to the conventional two‐level inverters as it also helps in reducing the size of the filter, thus makes the circuitry less complicated. In conventional multilevel inverter topologies, the number of devices increases with the increase of the number of output voltage levels, which in turn makes circuitry bulky and costly. Further, the boosting feature of the input voltage is also necessary for the application of multilevel inverters with renewable energy. Therefore, to reduce the count of devices, losses, and rating of devices, various switched‐capacitor multilevel inverter topologies are proposed. Switched‐capacitor multilevel inverter topologies (SCMLIs) can generate multiple voltage levels along with high voltage gain with a minimum number of devices. This paper gives a detailed overview of the recently introduced SCMLIs. The different SCMLIs have been categorized based on the number of levels and voltage gains. A detailed comparison has been introduced in this paper. Finally, few SCMLI topologies have been experimentally validated using the experimental results.

Summary In electric vehicles (EVs), considerable battery cells are cascaded in series for motor driving to improve the output voltage. The series combination of battery cells causes challenges like isolation of faulty cells, voltage unbalance, and slow charge equalization. Therefore, state‐of‐charge (SOC) and voltage equalization circuits are often used in industries to protect the battery cells. A nine‐level inverter circuit with a double voltage boost is proposed to reduce the above issues based on the switch‐capacitor (SC) principle. Unique features like self‐balancing, voltage boosting are attained, which cannot be achieved through traditional inverters. The proposed topology can operate at a wide range of modulation indices (ma) to produce different voltage levels. The absence of a back‐end H‐bridge in the proposed circuit offers low voltage stress across the semiconductors. The operating principle, capacitor sizing, and modulation approach are presented. Further, experimental tests are conducted at different loading conditions to verify the performance of the proposed circuit.
