Abstract
A power supply device with high output stability includes a bridge rectifier, a boost inductor, a power switch element, a first output stage circuit, a switch circuit, a transformer, a resonant capacitor, a sense resistor, a second output stage circuit, and a detection and control circuit. The detection and control circuit can detect a first peak voltage difference and a second peak voltage difference across the sense resistor. Furthermore, the detection and control circuit can control the first output stage circuit according to the first peak voltage difference and the second peak voltage difference.
