An AC output voltage from the secondary winding is rectified to generate a DC voltage, which is applied to a load. The 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 via an output stage of an optocoupler. The superposition circuit generates a superposition voltage that is applied to a current control circuit, which responds to the superposition voltage to vary a control current to a switching controller, which varies the frequency of the AC voltage to thereby vary the load current. A fault detection circuit senses a short in the output stage of the optocoupler to disable the operation of switching controller to prevent an overvoltage and an overcurrent."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting short circuit conditions in frequency control loop components","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.
