ABSTRACT:
A high voltage ultor power supply for a television receiver includes a ferroresonant transformer that is capable of operating over a substantial range of temperature without thereby introducing undesirably large changes in the ultor voltage. The ferroresonant transformer comprises a plurality of windings, a magnetizable core with first and second core sections, and a resonating capacitor. A first of the plurality of windings is wound on the first core section and coupled to a source of exciting current for generating magnetic flux in the core. A second of the plurality of windings is wound on the second core section. The varying magnetic flux that links the second winding generates an alternating polarity output voltage across that winding. To regulate the output voltage, the capacitor is coupled to one of the plurality of windings and develops a circulating current to produce a magnetic flux that aids in magnetically saturating the second core section. The first core section is operated in the magnetically unsaturated or linear region of the B-H loop characteristic of the magnetizable material forming the first core section. A high voltage circuit, responsive to the regulated output voltage, develops the television receiver ultor voltage. The material of the magnetically saturating second core section is selected to have a higher Curie temperature than that of the nonsaturating first core section, resulting in relatively small temperature dependent changes of the ultor voltage.
