ABSTRACT:
In a fly-back transformer, the tertiary winding for obtaining the secondary B power source is wound in a position where the coupling with the primary winding is weak and where it interlinks the leakage flux of the secondary winding with the primary winding, and the output of the tertiary winding is rectified during the scanning period of a horizontal deflection circuit of a television receiver. Accordingly, only the wave crest value of the ringing is made smaller, regardless of the shot pulse to be obtained within the secondary winding.
