Control circuit for e.g. insulated gate bipolar transistor, has circuit arrangement to modify signal and having parallel and voltage limiting circuits and capacitive component that are connected with knot of triggering circuit and/or switch

摘要

The circuit has a triggering circuit (1) to create a pulse width modulated triggering signal to trigger a semiconductor switch. A circuit arrangement is arranged between a control connection and the triggering circuit in series connection. The arrangement modifies the signal and has parallel (2) and voltage limiting circuits and a capacitive component, which are connected with a common knot of the triggering circuit and/or the switch.
