Method and circuit arrangement for switching a semiconductor switch

The invention relates to a method for switching a semiconductor switch from a first static switch state to a second static switch state by controlling a control connection (SHS) of the semiconductor switch (HS1), having the following steps: switching (S410, S420, S440, S450) the semiconductor switch...

Beschreibung
Zusammenfassung:	The invention relates to a method for switching a semiconductor switch from a first static switch state to a second static switch state by controlling a control connection (SHS) of the semiconductor switch (HS1), having the following steps: switching (S410, S420, S440, S450) the semiconductor switch in a current-controlled manner starting from the first static switch state in a first switching phase (S1, S2) by imprinting at least one first specified actuating current (IAS1) at the control connection (SHS) of the semiconductor switch (HS1) in a controlled manner, and switching (S430, S460) the semiconductor switch in a voltage-controlled manner in a second switching phase (S3) which follows the first switching phase (S1, S2) by applying at least one first specified actuating voltage (UAS1) to the control connection (SHS) of the semiconductor switch (HS1) in a controlled manner until the second static switch state is reached. In this manner, switching losses are reduced.
