Abstract: ABSTRACT This paper introduces a new switched‑inductor Z‑source inverter topology that employs a capacitor‑assisted inductor network, achieving a significantly higher voltage‑gain factor while simultaneously reducing capacitor voltage stress over an extended duty‑cycle range compared with existing Z‑source inverters. As the diode is replaced with a capacitor, this inverter is converted into a switched capacitor configuration, which increases the voltage gain. The operational principles, steady‐state analysis and design of passive elements, analysing the capacitor's voltage ripple and the inductor's current ripple, are conducted. Moreover, various n modes can be extended by the proposed topology, allowing significantly higher gains to be achieved. In addition, a detailed analysis of power loss is conducted on the analysed topology in terms of its efficiency. The accuracy and effectiveness of the proposed inverter are validated through both simulation and experimental findings.
