Abstract
A compact 150Â W photovoltaic inverter was developed using SiC devices, which integrated a maximum power point tracking charge controller and a direct current (DC) - alternating current (AC) converter into a single module. The DC-AC converter circuit was built with four SiC metal-oxidesemiconductor field-effect transistors, while the DC-DC converter circuit built with four SiC Schottky barrier diodes. An increase of the switching frequency led to the module of a reduced size (250Â ÃÂ 180Â ÃÂ 28Â mm3), which is just one third volume of a commercial Si-based inverter available today. Besides being compact, the conversion efficiency of the DC-AC converter was approximately 3% higher than that of the commercial Si-based inverter. In addition, the MPPT controller showed a conversion efficiency exceeding 96%, which raised the total efficiency under practical operation conditions up to 86%.
