Abstract
PURPOSE:To reduce power consumption by providing two resonance capacitors and making use of a flyback pulse from a deflection yoke to switch one of the resonance capacitors. CONSTITUTION:From the deflection yoke 9, a flyback pulse is inputted to the capacitors 14, 15 and is voltage-divided, then inputted to a clamper C consisting of diodes 16, 17, 18, and here, the reference level of an input waveform is set. With a level higher than such a reference level, a switching stansistor Tr 6 is turned on to connect a second resonance capacitor 4 in parallel with a first resonance capacitor 3, in order to provide a resonance operation realized by the two capacitors 3, 4 and the deflection yoke 9. When the horizontal frequency changes, a control transistor Tr 7 is turned on to operate by a control circuit 8, while Tr 6 is turned off, and the capacitor 4 is disconnected from the capacitor 3. Since a current flows through the Tr 6 only when it is turned on, the power consumption can be reduced.
