More Information
Summary:The invention relates to a method for detecting an arc (442) in a power semiconductor component (202), in which a component control element (408) associated with the power semiconductor component (202) transfers messages (N) to a superordinate control unit (35) via a first optical communication path (38). In the method, light (L) emitted from the arc (442) is transferred to the first optical communication path (38) by means of a second optical communication path (436), and said light (L) is coupled into the first optical communication path (38). As a result of this coupled-in light (L), the message transfer performed by the component control unit (408) via the first optical communication path (38) to the superordinate control unit (35) is disrupted. Because of said disrupted message transfer, the arc (442) is detected by the superordinate control unit (35).
