ABSTRACT:
The primary winding of a high leakage inductance power tranformer is coupled to a source of unregulated voltage and to a square wave voltage generator that includes first and second alternately conducting output switching transistors. A voltage controlled oscillator establishes the operating frequency of the voltage generator. A resonating capacitor is coupled to a transformer secondary winding that is loosely coupled with the primary winding. The capacitor forms a series tuned circuit with the leakage inductance between the primary and secondary windings of the transformer. The operating point of the tuned circuit voltage verses frequency characteristic curve determines the amplitude of the generally sinusoidal output voltage across the secondary winding, in accordance with the operating frequency of the square wave voltage generator. A feedback circuit senses the amplitude of the output voltage and varies the frequency of the voltage controlled oscillator to regulate the output voltage.
