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.
