ABSTRACT:
A high-voltage circuit for post focusing type color picture tube is disclosed in which a high voltage and a higher voltage are produced respectively from the middle and final stages of a voltage-multiplying rectifier circuit connected to the output winding of a fly-back transformer. The voltage-multiplying rectifier circuit comprises a plurality of rectifier elements and a plurality of capacitor elements. The fly-back transformer has its leakage inductance and the like adjusted so as to be tuned to the 7th or higher-order harmonic of fly-back pulses.
