Transformerless (TL) grid-connected photovoltaic (PV) inverters with a common-ground (CG) circuit architecture exhibit some excellent features in removing the leakage current concern and improving overall efficiency. However, ability to cope wide range of input voltage changes while maintaining output single power conversion stage is key technological challenge. Considering this, article at han...

The aim of this paper is to present a new topology single-phase transformerless inverters, which can be tied the local grid as low-scaled ac module system. proposed offers common ground between neutral point and negative terminal dc supply, properly alleviate concern variable mode voltage leakage current problems. This promising feature acquired by both switched-capacitor charge pumped circuit ...
