| Abstract |
This paper reports the different solutions we have studied to integrate current limiters with
SiC-based devices. Current limiters are highly needed for serial protection in almost the full range of
power applications, from telecommunication market to traction and energy distribution. Two types of
structures are presented, with two and three terminals, respectively. The two terminal device is based
on an ACCUMOSFET structure optimised for current limiting application. The three terminal device
is a special JFET design for efficient current pinch-off. Both structures have been optimised using
numerical simulations and then fabricated, characterized and checked in a real circuit. The current
limiting capability has been demonstrated and the superior potential of SiC is experimentally
demonstrated. |
