The Z‐source inverter was introduced to overcome shortcomings of voltage source inverter and current source inverter. In this paper, the concept of one switched‐inductor Z‐source inverter is extended to switched‐capacitor inductor ZSI with an impedance network. In the proposed inverter, capacitors are used instead of the side diodes of the one switched inductor Z‐source inverter. The proposed inverter has a higher boost factor compared to One SL‐ZSI and quasi‐ZSI. Also, it has lower voltage stress compared to similar inverters. The proposed inverter can be extended to n cases in cascade form. The components used in the proposed topology are lower than the SL‐ZSI. The analysis, derivation of boost factor, capacitor voltages, diode voltages, and switch voltages stress of the proposed inverter topology are carried out and are compared with the similar inverters. The advantages of the proposed structure are verified through simulation and implementation. The simulation is performed in MATLAB/SIMULINK. [ABSTRACT FROM AUTHOR]
