Television receiver high frequency regulated power supply including a low voltage ferroresonant transformer coupled to a step-up high voltage transformer

摘要

A source of high frequency alternating input voltage is coupled to the primary winding of a high frequency low voltage ferroresonant transformer of a television receiver power supply. A capacitor is coupled across the secondary output winding of the ferroresonant transformer, and generates a circulating current that magnetically saturates the secondary core portion of the transformer to regulate the alternating polarity output voltage developed across the secondary output winding. A step-up high voltage transformer includes a primary winding and a high voltage secondary winding tightly coupled to the step-up transformer primary winding. The regulated alternating polarity output voltage developed by the low voltage ferroresonant transformer is coupled to the primary winding of the step-up high voltage transformer without prior DC rectification of the ferroresonant transformer output voltage. The applied, regulated ferroresonant transformer output voltage develops a regulated high voltage across the step-up transformer high voltage secondary winding. A high voltage rectifier arrangement develops an ultor voltage from the regulated high voltage.
