Abstract

PURPOSE:To avoid the variation of the output characteristics caused by dispersion of the circuit constitution parts for the horizontal drive circuit of the TV picture receiver by giving rectification and smoothing to the horizontal drive pulse to lead out the DC output of the pulse and then controlling the scale and the duration of the drive pulse based on the above DC output. CONSTITUTION:Horizontal oscillation circuit 1 generating the horizontal drive pulse is provided, along with Tr10 using the output of waveform shaping transistor Tr14 which detects the amplitude of the drive pulse of circuit 1 as the input. And the output of Tr10 is applied to the base of horizontal drive Tr14. At the same time, the duration of the horizontal drive pulse is detected by Zener diode 6 and variable resistance 7, and this detected output undergoes rectification/amplification through diode 25 and capacitor 26 to obtain the DC output which is then applied to winding 24 of drive transformer 16 which uses the output of Tr14 as the input to control both the duration and amplitude of the horizontal drive pulse. Then the output of 3rd winding 17 of transformer 15 is supplied to horizontal output circuit 18.
