Application of SiC Normally-On JFETs in Photovoltaic Power Converters: Suitable Circuits and Potentials
Photovoltaic systems have been considered as one of most promising fields of application for SiC semiconductors mainly due to the requirements for very high efficiency values. Several other system aspects like volume and cost may also profit from the interesting characteristics of such innovative devices. One promising example is the vertical JFET, mainly due to its relative structural simplicity. Nevertheless, its inherent normally-on characteristic calls for especially tailored topologies, as some suitable applications for photovoltaic systems will be presented.
