“…These circuits employ capacitors, power switches, and/or diodes to convert a fixed DC-link voltage into multilevel voltage, enabling inductorless and transformerless operation with voltage-boosting capabilities and inherent capacitor self-voltage balancing. Although SC integration in DC-DC converters has been extensively studied and commercialized, the application to multilevel AC-voltage generation is still a growing area of research [44][45][46][47][48]. There are considerations related to component count, complexity, and the large value of current stress imposed by the input DC source which limit the expected power range of these converters.…”

In this article, a generalized control scheme is proposed to extend the operating range of three-phase hybrid cascaded H-bridge (HCHB) inverters into various voltage levels without necessitating alterations to the core structure or the integration of additional H-bridge submodules. This study addresses a critical challenge related to capacitor voltage drift at various modulation indices and power factors, which is a serious impediment to various applications. To overcome this challenge, a novel balancing control scheme has been developed based on the injection of two independent offset voltages to simultaneously control the DC-link and flying capacitors. A distinctive aspect of the proposed technique involves adjusting the common reference voltage to attain the nearest level in the same cluster, thereby mitigating the insufficiency of redundant switching states. The effectiveness of the proposed technique to regulate the capacitor voltages at various operating conditions has been verified through simulation and experimental results.
