Patents by Inventor ANDREAS LANDERER

ANDREAS LANDERER 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).

  • Patent number: 8817430
    Abstract: An AC voltage controller has two transistors which can be positioned between two AC voltage terminals in series with a load. The two transistors are connected in series in such a way that their respective source terminals are connected to one another. The AC voltage controller also contains a signal generator for generating a switching signal for actuating the two transistors, a buffer which is connected downstream of the signal generator and which is set by the signal generator in order to actuate the two transistors. An actuation circuit or driver circuit is connected downstream of the buffer, for the purpose of actuating the two transistors in accordance with the set state of the buffer. A current-limiting circuit is provided for limiting or switching off the current through the two transistors in the case of an excessively large current through the load.
