  • Half bridge for an active rectifier having an overvoltage protection
    Patent number: 9973105
    Abstract: A half bridge for an active rectifier having an alternating-voltage connection, a positive direct-voltage connection, as well as a ground connection, a first switch element connecting the alternating-voltage connection to the ground connection; a second switch element connecting the alternating-voltage connection to the positive direct-voltage connection, a first control element being connected to the first switch element for switching the first switch element; a connection of a first capacitor being connected to a voltage supply connection of the first control element; the positive direct-voltage connection being connected via a first diode in the forward direction to the one connection of the first capacitor; the first capacitor being connected in parallel to a series connection of the first switch element and the second switch element.
