A transistor arrangement has first and second terminals and a control terminal which sets a current flow between the first and second terminals, and a signal conditioning device which applies a transistor control voltage to the control terminal in a manner dependent on a differential voltage present between the first and second terminals, and a driving apparatus is assigned to the signal conditioning device and switches the latter between at least two operating modes.

Transistor arrangement for rectifier and inverter

A control circuit for controlling an electronic circuit, which has a current path through a semiconductor switch and a line; when the semiconductor switch is switched, the inductance of the line and/or of a component in the current path producing an excess voltage between a first and a second current-carrying terminal of the semiconductor switch; the control circuit having a controllable current source for charging or discharging a charge-controlled gate of the semiconductor switch with the aid of a control current, as well as a control unit; the control unit controlling the current source in such a manner, that in the case of a switching operation, the terminal voltage across the current-carrying terminals of the semiconductor switch does not exceed a predefined setpoint terminal voltage.
