Deflection current/high voltage integration type power supply
 A deflection current/high voltage integration type power supply has a flyback transformer having a primary winding and a secondary winding; a series circuit of a deflection coil and a first capacitor, connected in series to the primary winding of the flyback transformer; a resonance capacitor connected in parallel to the series circuit of the deflection coil and the first capacitor; a first switching element, connected in parallel with the series circuit of the deflection coil and the first capacitor, to be turned on/turned off by a drive signal so that a high voltage is generated at the secondary winding of the flyback transformer and a deflection current flows in the deflection coil; a parallel connection circuit of a second switching element and a second capacitor, connected in series to the primary winding of the flyback transformer; and a switching control means to control the deflection current flowing in the deflection coil and the high voltage generated at the secondary winding of the flyback transformer by controlling the on-timing and the off-timing of the second switching element in approximate synchronism with the drive signal.
