Abstract:
Overcurrent breakers are essential and also challenging for smart AC or DC grids. For lower voltages up to several 100 V full-silicon solutions can be used instead of hybrid or mechanical solutions for high voltages. In the literature several solutions with JFETs are described. Due to the exotic JFET semiconductor, a different solution with IGBTs, whose gate-emitter voltage is lowered to reach a defined cutoff current, is shown within this paper. This concept is explained and measurements are presented.
