Abstract: The present invention relates to a dynamic voltage gain common ground switched capacitor seven-level inverter (100) for converting a low-voltage direct current input into a multilevel alternating current output comprises a DC source (Vdc), an input inductor (Lin) forming a switched boost circuit, a switched-capacitor network including a first capacitor (C1), a second capacitor (C2), and a third capacitor (C3), a plurality of bidirectional switches, a plurality of unidirectional switches, and a T- type switching arrangement. The switched boost circuit selectively operates in static and dynamic boost modes by controlling a charging and discharging duty ratio of the input inductor (Lin) to provide selectable voltage gain while generating seven output voltage levels. The common-ground configuration reduces leakage current and electromagnetic interference, whereas the switched-capacitor network maintains self-voltage balancing without an additional balancing circuit. The present invention enables compact, efficient, and scalable power conversion suitable for renewable energy and low-voltage power applications.
