Abstract

This paper proposes new active switched-capacitor and switched-inductor Z-source inverter (ASC/SL-ZSI) topologies, whichcan provide a higher boost ability with a small shoot-through time. The proposed ASC/SL-ZSIs inherit all of the advantages ofthe classical ZSI, and have a stronger voltage boost inversion ability when compared with the classical ZSI. Thus, the output acvoltage quality is significantly improved. In addition, more cells can be cascaded in the impedance network in order to obtain avery high boost ability. The proposed topologies can be applied to photovoltaic or fuel-cell generation systems with low-voltagerenewal sources due to their wide range of obtainable voltages. Both simulations and the experimental results are carried out inorder to verify performance of the proposed topologies.
