The requirement of a boosting aspect for the power electronic converter is essential for the fuel cell, solar PV, and battery-based applications as the generated voltage is of low voltage magnitude. In these low-voltage applications, a new boost inverter topology has been suggested, where the power conversion will happen in a single-stage instead of two-stage (dc�dc converter + two-level inverter). The proposed topology consists of 11 power semiconductor devices, one switched capacitor unit, and two dc voltage sources that are arranged in the magnitude of 1:3. This arrangement is able to achieve an output voltage of 15 levels with a boosting factor of 1.75. The other advantages of the designed topology have been the reduced device count with the self-balancing of capacitor voltage and improved efficiency with better power loss sharing among the switches. By accumulating additional switched-capacitor units to the proposed basic structure, the proposed inverter can be extended to support a greater number of levels and a higher voltage gain. A comprehensive assessment has been accomplished with single-source and dual-source topologies, and the proposed topology shows the improved design. A low-power laboratory porotype has been used to endorse the proposed topology with real-time conditions. © 2022 John Wiley & Sons, Ltd.
