Document Type and Number:
Japanese Patent JP2635553
Kind Code:
B2
Abstract:
A television deflection apparatus includes a deflection winding coupled to a retrace capacitance to form a retrace resonant circuit. A power transistor switch is coupled to the retrace resonant circuit for generating alternating current in the retrace resonant circuit. The power transistor switch energizes a primary winding of a flyback transformer that supplies a first voltage across a secondary winding of the flyback transformer. The first voltage is coupled to an inductance for forming an upramping current in the inductance. The upramping current in the inductance is coupled to the base electrode of the power transistor switch, causing the power transistor switch to be conductive during the second half of trace. A second switch, that is responsive to a deflection rate input signal, couples to the base electrode of the power transistor switch a negative supply voltage that turns off the power transistor to initiate the retrace interval.
