An AC output voltage from the secondary winding is rectified to generate a DC voltage, which is applied to a load. The magnitude of a current flowing through the load is sensed and compared to a reference magnitude to produce a feedback signal. The feedback signal controls a voltage superposition circuit, which produces a superposition voltage. The superposition voltage is applied to an input node of a current control circuit. The current control circuit responds to the superposition voltage to vary a magnitude of a control current to a switching controller in the DC to-AC inverter. The switching controller is responsive to the control current magnitude to vary the frequency of the AC voltage and to thereby vary the load current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency control method for self-oscillating circuit","description":"A DC-to-AC inverter provides an AC voltage to the primary winding of an output isolation transformer having at least one secondary winding.
