  • Circuit for generating a deflection current through a coil for the vertical deflection in a display tube
    Patent number: 4024433
    Abstract: A field deflection output circuit in which the end of the deflection coil which is not connected to the output amplifier is coupled with a terminal of a voltage source during the scan period and with the other terminal of this voltage source during the flyback period.
    Type: Grant
    Filed: September 17, 1975
    Date of Patent: May 17, 1977
    Assignee: U.S. Philips Corporation
    Inventor: Jan Abraham Cornelis Korver
  • Circuit arrangement for generating a deflection current through a coil for vertical deflection in a display tube
    Patent number: 3934173
    Abstract: A field deflection output circuit in which the deflector coil is divided in two halves which are connected between the terminals of a direct-voltage source, in series during the trace interval and in parallel in the retrace interval. As a result the retrace interval may be given the correct duration whilst dissipation is kept low so as to enable the circuit arrangement to be integrated in a semiconductor body.
