    A horizontal deflection circuit comprises a deflection winding, an output deflection circuit for generating deflection current and retrace pulses, an oscillator and driver circuit for providing drive signals to the output deflection circuit, a frequency and phase control circuit for synchronizing the deflection current with incoming sync pulses, and a correction circuit. The correction circuit corrects for variations in initiation of retrace which are not adjusted by the frequency and phase control circuit, such as caused by variations in storage time delay of an output transistor. The correction circuit includes a sawtooth generator for obtaining a sawtooth voltage from a retrace pulse and a peak separator to which the sawtooth voltage is coupled for generating voltage pulses for providing a correction voltage to the oscillator and driver circuit.

    The invention relates to television technology and can be used in horizontal deviations in television receivers.
    The old-fashioned for the formation of a direct current scan, containing a phase discriminator, the input of which is an input of synchronizing pulses, while the output of the phase discriminator is connected through a series switch, a buffer amplifier, a master oscillator and an output amplifier to the primary winding of the output switch, the output switch, the output switch, the output switch, and the output switch. one secondary winding of which is connected to the high-voltage unit, and the other to the second input of the phase discriminator 1.
    The known device is characterized by insufficient linearity and voltage stability, especially when the video load of the high-voltage reading source of the television tube is strong.
    The purpose of the invention is to increase the linearity and stability of the stress.
    To do this, a horizontal scanning voltage device containing a phase discriminator, the input of which is a synchronized and 1.1x input.
    impulses, while the output of the phase disc .nator is connected via a series-connected switch, buffer amplifier, master oscillator and output amplifier to the primary winding of the output horizontal transformer, one secondary winding of which is connected to the high-voltage unit, and the other to the second input of the phase discriminator is entered A correction block, the input of which is connected to the output of the input third secondary winding of the output horizontal transformer, and the output of the correction unit is connected to the switch input tel.
    The drawing shows a structural electrical circuit of a device for forming a horizontal scanning voltage.
    The device contains phase dicrimiator 1, switch 2, buffer force | el, o, master oscillator 4, output amplifier 5, output horizontal transformer G, in which 1 is primary, I is the first secondary, 111 is the second secondary, and iV is the third secondary winding; high-voltage unit 7 and block 8 correction.
    icTpoiiCTBo works as follows.
    The input phase discriminator 1 receives synchronizing pulses, the phase and period of which are compared with the phase and period of the pulses coming from the secondary winding III of the output line of the transformer 6. From the output of the phase discriminator 1, the control voltage through the switch 2 and the buffer amplifier 3 is fed to the input of generator 4 for controlling the frequency of the oscillations generated. From the output of the master oscillator 4, voltage pulses are fed to the output amplifier 5, the load of which is a winding winding I of the output horizontal transformer 6. The secondary winding II of the output horizontal transformer is connected to a high voltage unit 7, where a high voltage is generated to supply the accelerating electrodes electronic tv tube. The third secondary winding IV is connected to the input of the correction unit 8, the output voltage of which, arriving at the input of the switch 2, performs an additional adjustment of the frequency and phase of the horizontal deflection pulses.
