Title:
HORIZONTAL OUTPUT CIRCUIT
Document Type and Number:
Japanese Patent JP3932703
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce power consumption by reducing a variable range of a DC power source while holding a function to cope with frequency in a wide range.
SOLUTION: In a variable frequency horizontal deflection circuit (multi scan deflection circuit), deflected frequency correspondence is added to DC voltage control, voltage control at both ends of a deflection coil is added by switch control by a synchronizing separator circuit 3 and a frequency discriminating circuit 2. Thus, the power consumption is reduced by reducing the variable quantity of the DC voltage.
