A method for switching power transistors in a power transistor circuit. The power transistors each have a gate, which is driven sequentially by at least three control values in the case of a switch-on sequence and/or a switch-off sequence. A switchover occurs between the control values at specific times. The specific times are determined or modified by a controller, which is driven by a Miller plateau detector for detecting a Miller plateau in a gate-source voltage of the respective power transistor.

Method for switching power transistors

A method for actuating a controllable semiconductor switch by switching the switch on an off in phases in a controlled manner using a control signal is disclosed. The method includes starting a time measurement at the beginning of at least one phase of the phase-wise on-and-off switching procedure to ascertain a time duration, wherein the time measurement is continued until a phase following the at least one phase of the phase-wise on-and-off switching procedure begins. The ascertained time duration is compared with a specified maximal time duration. If the ascertained time duration exceeds the specified maximal time duration, the semiconductor switch is actuated such that the semiconductor switch is switched into a specified operating state.
