Abstract |
This paper proposes a simple AC solid state variable current limiter based on two commercially available 1200 V SiC JFETs [1], the JFET conguration requires no active regulation and has intrinsically fast response time to short circuit conditions with the benet of simplicity and low cost. This circuit is intended as an additional current limiting circuit for high power ampliers where the current limitation reaction time is in the seconds range. This demoboard was built for fast current limitation with high power ampliers to test PFC (Power Factor Correction) circuit. This paper presents the circuit of a working demonstrator with experimental verication and compares the experimental results with simulations. |
