Abstract
SiC semiconductors offer very interesting characteristics and can be considered as a future trend in
photovoltaic converter technology. The vertical JFET is an example of a very promising device, mainly
due to its relative structural simplicity. Nevertheless, its inherent normally-on characteristic calls for
specially tailored topologies that will be presented and discussed in this publication.
