A Step-Up 5-Level Transformer-Less Switched Capacitor Inverter Without Leakage Current for PV System Application

This paper proposes a 1-ϕ transformer-less inverter for grid-tied PV systems. The proposed inverter has the capability to produce five distinct voltage levels at the output stage. Moreover, it is a compact switched-capacitor (SC) based design that incorporates eight power switches, an ultra-fast pow...
