  • High speed flyback circuit for magnetic yoke
    Patent number: 4677352
    Abstract: A deflection drive circuit (15) for an inductive yoke (11) used with a raster scanned cathode ray tube rapidly interrupts current then reverses voltage applied to the yoke (11) during flyback. MOSFETs (Q32, Q47) are used to control current flow to the yoke. The current is interrupted by one MOSFET (Q32) being gated "OFF", after which current is permitted to flow to a capacitor (C51). At a preselected time, a second MOSFET (Q47) is gated on to admit reverse flow of current from the capacitor (C51) to the yoke (11). The second MOSFET (Q47) is gated "ON" by a circuit which includes a third MOSFET (Q57) and a pulse transformer (T59).Advantages include an ability to rapidly effect flyback without interfering with the forward scanning ability of the deflection drive circuit 15.
