Abstract
A high frequency ferroresonant transformer is driven by a high frequency power source coupled to a drive winding of the ferroresonant transformer. Around saturating portions of the core are wound a low voltage winding for providing a B+ scanning voltage and a high voltage winding for providing an ultor voltage. Tuning of the ferroresonant transformer for regulating the B+ and ultor voltages may be provided by the high voltage winding distributed capacitance, for example, or by a discrete capacitor coupled across a winding associated with the saturating portions of the core, for example.
