摘要： An electronic circuit comprises at least one semiconductor switch mounted with its switching path in series with an inductive load to be triggered, and at least one freewheeling element that interacts with the semiconductor switch during switching phases and is also mounted in series with the load. A control unit controls a control connection of the semiconductor switch with a variable control current as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path. A method for triggering a semiconductor switch of such a circuit, triggered by a variable control current for switching, the control current predefined as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path.

A control unit controls a control connection of the semiconductor switch with a variable control current as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path. A method for triggering a semiconductor switch of such a circuit, triggered by a variable control current for switching, the control current predefined as a function of the time profile of a voltage measured at the freewheeling element and/or as a function of the time profile of the voltage measured at the switching path. The electronic circuit according to the disclosure is advantageously used for triggering semiconductor switches of a bridge inverter circuit, in particular for operating an EC motor.
