  • Method of and driver circuit for operating a semiconductor power switch
    Patent number: 8258823
    Abstract: To operate a semiconductor power switch having a control electrode and a reference electrode in response to first and second switching commands, a control voltage between a first electric pole and a second electric pole is provided. Upon each first switching command, the control electrode is coupled to the first electric pole, and the reference electrode is coupled to the second electric pole; and upon each second switching command, the control electrode is coupled to the second electric pole, and the reference electrode is coupled to the first electric pole. Upon each switching command, continuously transitioning an electric potential of the one of the control and reference electrodes during a first transition period, and continuously transitioning an electric potential of the respective other of the control and reference electrodes during a second transition period occurs, wherein the first transition period beginning before and ending after the second transition period.
