DEVICE AND METHOD FOR THE SELF-REINFORCING ACTUATION OF A CHARGE-CONTROLLED SWITCHING ELEMENT, AND USE OF A TRANSFORMER

摘要

The invention relates to a circuit device (100) and a method for the self-reinforcing actuation of a charge-controlled switching element (20). The switching device (100) comprises the following: a charge-controlled switching element (20) with a first load current connection (22) for the input of a load current to be switched, a second load current connection (24) for the output of the load current to be switched, and a control connection (26) for controlling the switching element (20) by means of a control signal, wherein the first and the second load current connections (22, 24) are integrated into a load current path (10) of the circuit device (100), and the control connection (26) is integrated into a control current path (13) of the circuit device (100); a control unit (30) for providing the control signal; and a coupling element (40) for transmitting energy from the load current path (10) into the control current path (13) in a galvanically isolated manner. The invention further relates to the use of a transformer.
