ABSTRACT:
Wave-chopping is performed by means of an active switch, said switch being unidirectional in voltage and bidirectional in current and connected in series with a secondary winding of the horizontal-scanning transformer. The secondary winding is connected in series with an inductance coil which is not coupled to the transformer and with a polarized capacitor, the output voltage being collected at the terminals of the capacitor.
The power supply circuit is employed in video-frequency receivers having low dissipation.
