  • Half-bridge circuit protected against short circuits and having semiconductor switches
    Patent number: 8593773
    Abstract: A circuit arrangement with two semiconductor switches connected in series between a first potential connection and a second potential connection is provided. The circuit arrangement may include an inductive element connected in series between the two potential connections and by elements of an action chain of such a nature that, under predefined conditions, a voltage drop across the inductive element effects the switching off of at least one of the semiconductor switches.
