Self-regulating saturating core television receiver power supply

Abstract

A self-regulating, saturating core power supply for a television receiver includes a magnetizable core having first, second and third core sections. A primary winding is wound around the first core section and an output secondary winding is wound around the second core section. The third core section provides a magnetic circuit path for magnetic flux lines that link both windings. The primary winding is coupled to a source of alternating input voltage for developing an alternating polarity output voltage across the secondary winding. A resonating capacitor is coupled to the secondary winding for generating a current therein that aids in producing substantial magnetic saturation of the third core section twice during each cycle of the alternating polarity output voltage to thereby regulate the output voltage. The second core section remains substantially unsaturated during the entirety of each cycle. The regulated output voltage may be used to develop direct supply voltages for the television receiver such as the B+ scan supply voltage and the ultor high voltage.
