Title:
HORIZONTAL DEFLECTION CIRCUIT
Document Type and Number:
Japanese Patent JPS60130970
Kind Code:
A
Abstract:
PURPOSE: To make a horizontal deflection current stable by detecting the horizontal deflection voltage and controlling a supply voltage to a horizontal output transistor (TR) by means of the detected output.
CONSTITUTION: Capacitors Cr, Cg, Cb for S-shaped correction, horizontal deflection coils 4R, 4G, 4B and DC constant current sources 5R, 5G, 5B for horizontal centering are connected to a collector of the horizontal output TRQ. A horizontal deflection voltage Eh is applied to a base of a TRQ2 via a sample and hold circuit 6 and an amplifier 7. Since the negative feedback is applied and the voltage Eh is kept constant, no registration is changed.
