Abstract
In an insulated resonance circuit device, a first resonance circuit includes first and second LC resonance circuits electromagnetically coupled to each other and electrically insulated from each other, oscillates at a predetermined first resonance frequency based on an input AC voltage, and outputs an oscillation signal voltage. The second resonance circuit having a second resonance frequency substantially identical to the first resonance frequency resonates with the oscillation signal voltage to detect the oscillation signal voltage, and outputs the detected oscillation signal voltage. A control circuit compare the oscillation signal voltage from the second resonance circuit with a comparison signal voltage for obtaining a predetermined target output voltage and/or a predetermined target output current to generate and output gate signals for controlling a rectifier circuit.
