Zusammenfassung:	Power supply devices are provided. The power supply device includes a power converter and a control circuit. The control circuit is coupled to the power converter. The power converter is configured to convert an input power to provide an output power. The control circuit is configured to receive a control signal and provide a dummy current according to the control signal and the output power, such that the sum of the current value of the dummy current and the current value of the output power is greater than or equal to a threshold value, thereby the power converter converts the input power in soft switching.
