Abstract

This paper proposes a modified inverter topology called Embedded Enhanced-Boost Z-Source Inverter (EEB- ZSI). Compared with the prior-art Enhanced-Boost Z-Source Inverter (EB-ZSI), the proposed topology features that the dc sources like PV panels can be embedded into a symmetrical impedance network. In this way, the dc current becomes continuous. More importantly, the voltage stress across the switching devices is lower, while a large conversion ratio is maintained. The proposed Z-source inverter is benchmarked with selected topologies in terms of the conversion ratio, voltage gain, and stresses on the devices. Simulation and experimental results are provided to validate the analysis.

Keywords
