UtiIitY-interactive photovoltaic power conditioning systems with forward converter for domestic applications

摘要

Various utility-interactive photovoltaic power conditioning systematic have been reported. In general, it could be said that such photovoltaic power conditioning systems have been approaching the ideal, i.e. high efficiency, high performance etc. However, the system cost including that for power converters and solar cells still prevents widespread application. A simple utility-interactive photovoltaic power conditioning system with a forward converter and an innovative lossless srubber circuit are proposed. They are easy to utilise and complement each other. The system operation is confirmed by simulation analysis and experiment.
