Abstract
A power supply device includes a rectifier module, an excitation module, a switch module, a transformer module, a first output module, a second output module, a control module and a logic module. The first and second output modules receive first and second transformed voltages of the transformer module to generate first and second output voltages. The control module determines whether the first output voltage is abnormal according to first and second slopes of the first and second output voltages. When the first output voltage is abnormal, the control module generates a comparison result according to the first slope and a reference slope. The logic module generates a logic signal according to a reference voltage, the first output voltage and the comparison result. The control module controls the power supply device to enter a short current protection or a under voltage protection according to the logic signal.
