Abstract

A highly efficient MOSFET inverter for single-phase grid-connected photovoltaic power generation systems is presented in this paper. It is a full-MOSFET version of the conventional transformerless full-bridge inverter with dual L-C filters using unipolar PWM. The key idea lies on smart pre switching(SPS), which can make the large switching loss due to a poor reverse recovery of the MOSFET's body diode reduced dramatically. The validity of the proposed inverter is verified by experiment.
