Method and circuit arrangement for actuating a semiconductor switch |
摘要 |
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. |

1. A method for actuating a controllable semiconductor switch using a control signal by controlled, stepwise switching-on and switching-off, the method comprising:
starting a time measurement at a beginning of at least one step of the stepwise switching-on and switching off to determine a duration, wherein the time measurement is continued until a beginning of step following the at least one step of the stepwise switching-on and switching off, comparing the determined duration with a preset maximum duration, and in response to determining that the determined duration exceeds the preset maximum duration, actuating the semiconductor switch such that the semiconductor switch is switched into a preset operating state. |
