Abstract
In a resonant regulator power supply, a resonant circuit is coupled to a source of alternating input voltage that is controllable in operating frequency. A power transformer primary winding is coupled across the capacitive element of the resonant circuit for generating an output voltage across a secondary winding. A control circuit varies the operating frequency in a negative feedback loop to regulate the output voltage on the positive slope of the frequency characteristic curve. A frequency limiting circuit prevents the operating frequency from passing through the resonance frequency of the resonant circuit.
