Abstract
A power supply device has a first output port, a second output port and a power delivery control module. The power delivery control module compares the first output voltage value and the second output voltage value to determine a reference voltage value, and determines the optimized voltage value according to the total output power value, the reference voltage value, and a rated output current of an AC/DC converting module. The power delivery control module controls the AC/DC converting module to convert the AC input voltage to an optimized voltage, so that when the first and second DC/DC converting modules receive the optimized voltage and convert it to the first and second output voltages respectively, the voltage drop is reduced, the conversion loss is reduced, and the conversion efficiency of the power supply device is improved.
