Title: Television line deflection stage
IPC: H03K4/83
Filed: 1972-04-26
Abstract: 1370512 Line time base circuits; controlled non-linear inductors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 April 1972 [29 April 1971] 19354/72 Headings H3B and H3T [Also in Division H1] A line time base of the type in which respective switches are conducting during scan and flyback and in which energy loss is restored by current through a saturable inductor controlled by means of an inductor in parallel therewith, the inductor coils are wound on the outer legs of a core and a saturation control coil is wound on the central leg. In the circuit shown the first part of the scan is provided by energy discharging from the deflection coil system flowing through diode D 1 and the second part by current flowing through thyristor T Y1 . To initiate a flyback a thyristor T Y2  is fired and this switches off T Y1  and allows oscillation to occur in L1 C2, C3, C4 and L6. In addition a saturable inductor L8 charges through T Y2 . During the subsequent scan the inductor L8 discharges into C2, C3 and C4 via L6 to replace circuit losses. When the voltage across the capacitor exceeds the supply voltage, diode D3 becomes conductive connecting L7 in parallel with L8 and the discharge current of L8 is diverted via D3 into L7 so that L7 is effectively in parallel with L8, reducing the respective inductance thereof. The combined inductance of L7 and L8 and thus the energy supplied to the circuit is controlled by a winding at L9 fed from the output circuit coil L5 via an amplifier 2 so as to vary the saturation of the leg of the core on which L7 is wound. By virtue of an air gap in the leg carrying L8 the inductance of this winding is not varied during the flyback so long as D3 is not conducting. Fig. 2 shows the air gap in the core of L8 and the corresponding gaps in the other legs filled with magnetic material. The gap in leg 31 may be only partly filled so that the knee of the BH is rounded. It is stated that alternatively a gap in leg 8 may be provided by shortening one section of the leg.  Thyristor T Y1  is controlled via C5 from a tap on winding 8 and capacitor C1 provides S correction.
