Abstract

According to an embodiment of a switch device, the switch device includes a first switch, a second switch and an evaluation circuit. The evaluation circuit is configured to evaluate a temporal behavior of a node between the first switch and the second switch to detect a possible fault condition of at least one of the first switch or the second switch. A corresponding fault detection method for a switch device having a first switch and a second switch is also provided.

Description

technical field [0001] The present application relates to switchgear and associated methods. Background technique [0002] Switching devices are generally used to selectively electrically couple two terminals of the switching device. In this way, eg a power switching device may be used to selectively couple a load to a supply voltage, eg by coupling a supply voltage to a first terminal of the switching device and a load to a second terminal of the switching device. [0003] For some applications, eg for high voltage applications, conventional mechanical switches are used. However, as the capabilities of semiconductor switches, such as power transistors, increase, it becomes increasingly desirable to use semiconductor switches in applications where conventional mechanical switches are also used. [0004] For some applications, such as safety-related applications, it is desirable or even necessary to be able to obtain information about the state of the switch. For example, ...
