Abstract: A power supply device is provided. The power supply device includes a power converter and a controller. The controller controls the power converter to generate an output power. The controller includes a first detection circuit and a second detection circuit. The first detection circuit detects the output power to obtain a first detection result. The first detection result is a variation of an output current value of the output power. The second detection circuit detects electrical characteristics other than the output current value to obtain a second detection result. The controller determines whether to limit output of the output power according to a relationship between the first detection result and the second detection result.
