Title:
FLYBACK TRANSFORMER
Document Type and Number:
Japanese Patent JP3749771
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide such a flyback transformer that can realize high-voltage insulation easily at a low cost, can reduce alternating electric field, and can be handled easily.
SOLUTION: Diodes 3a to 3d for rectifying high voltage are serially connected on the output side of respective high-voltage coils of secondary side where a flyback transformer for supplying high voltage to a Braun tube is divided, and a high-voltage capacitor is connected to the cathode side of final diode. In addition, a high-voltage output line is passed through another core other than the core for flyback transformer, and this core is used as a reverse-phase pulse induction transformer 31 provided with a winding 24 for inducing pulse reverse to horizontal pulse for driving deflection yoke. The pulse reverse to the horizontal pulse for driving deflection yoke is superimposed on the high- voltage output line, thereby reducing alternating electric field radiating from the Braun tube.
