Device for triggering a switch element has a source of signals linked to a control input for a switch element generating a control signal to determine the switching status of the switch element.

摘要

A source of signals (3,5) links to a control input for a switch element (T1,T2) and generates a control signal to determine the switching status of the switch element. A test element (8,10) detects a test signal (IDRAIN,USOURCE) that returns a current flowing through the switch element or a voltage at the output of the switch element. An Independent claim is also included for a method for triggering a controllable switch element.
