Patents by Inventor Christoph Friederich

Christoph Friederich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230349975
    Abstract: A method and a device for monitoring a plurality of parallel-connected semiconductor switches. The method includes subjecting the plurality of semiconductor switches to a heating pulse, in which a predefined load current flows for a predefined period of time in order to achieve a predefined temperature change of the semiconductor switches, a variable of a semiconductor switch to be monitored from the plurality of semiconductor switches being detected both before and after the application of the heating pulse, and a state of the semiconductor switch to be monitored and/or an electronics packaging, which corresponds to the semiconductor switch to be monitored, being ascertained on the basis of a deviation of the change of the at least one variable from a predefined reference value. The method enables a measurement of individual semiconductor switches to be monitored from the plurality of semiconductor switches.
