A hybrid switched inductor quasi-Z-source dc-dc converter with cascaded switched capacitor arrangement to increase the voltage gain is proposed in this article, where the operation principle and detailed mathematical analysis are presented.Abstract:
A hybrid switched inductor quasi-Z-source dc-dc converter with cascaded switched capacitor arrangement to increase the voltage gain is proposed in this paper. The proposed converter has higher voltage gain at lower duty ratio, reduced voltage stress across all the components compared to conventional impedance source converter configurations. The voltage gain is almost two times the two switched inductor quasi-Z-source inverter arrangement. The operation principle and detailed mathematical analysis is presented. The design equations for the passive components are formulated. The proposed converter is then compared with other existing converters reported in literature. Simulation results verifies the mathematical analysis of proposed converter.read more

Z-source inverter
TL;DR: The Z-source converter employs a unique impedance network to couple the converter main circuit to the power source, thus providing unique features that cannot be obtained in the traditional voltage-source (or voltage-fed) and current-source converters where a capacitor and inductor are used, respectively.
