摘要：A process for the short circuit - and, via load disconnection with half -components on silicon carbide (sic) - base, characterised in that, as a semiconductorcomponent is a jfet (1) in the function as an active limiter is used, wherein a
predeterminable current (i) and a predeterminable gate - source - voltage (u) a voltagethan the resulting voltage drop (u) , and the gate - source - voltage (u) as a function ofthe instantaneously flowing current (i) during the turn-off process is regulated in such away that the voltage (u) immediately after depletion or clearance of charge carriers thegreatest possible value, of the for the jfet (1) and the circuit to be disconnected is notcritical, assumes and retains this value.
