Abstract
A power supply device with high output stability includes a voltage divider circuit, a full bridge rectifier, a resonant capacitor, a first transformer, a second transformer, a first switch element, a second switch element, a third switch element, an output stage circuit, and a detection and control circuit. The first switch element selectively couples the second transformer to the first transformer. The second switch element selectively couples the output stage circuit to the first transformer. The third switch element selectively couples the output stage circuit to the second transformer. The detection and control circuit appropriately controls the first switch element, the second switch element, and the third switch element according to a divided voltage from the voltage divider circuit and a capacitive voltage from the resonant capacitor.
