Abstract

The proposed photovoltaic Micro Inverter is based on three port fly back with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the transformers leakage energy. A diode is involved to prevent the reverse current from power decoupling capacitor to PV panel.
