摘要： Composition and evaluation are shown about the feedback circuit and its circuit constants which stabilize the direct-current output voltage obtained by rectifying a high-frequency carrier outputted from a resonance circuit against a wide range of load. An equivalent power supply is introduced, including a virtual resonance circuit and a virtual rectification circuit. The virtual resonance circuit, supplied with the same input with a resonance circuit, outputs the envelop of such the carrier that is outputted by the resonance circuit. The virtual rectification circuit, supplied with the envelop of the carrier, works as a first-order delay and outputs the direct-current voltage equivalent with the output of a rectification circuit. The equivalent power supply is described by the system of differential equations. The sufficient condition that the system of differential equations becomes stable is given. The feedback circuit satisfying the sufficient condition is shown to be stable by simulation.
