Claim Text:
1. A power supply device for outputting a first direct current voltage signal of a first voltage and a second direct current voltage signal of a second voltage to a load, the power supply device comprising: an alternating current-direct current conversion unit configured to provide a source direct current voltage signal; a first direct current-direct current conversion unit configured to generate the first direct current voltage signal and the second direct current voltage signal according to the source direct current voltage signal, output the first direct current voltage signal to the load through a first output interface and output the second direct current voltage signal to the load through a second output interface; a reference voltage signal generation unit configured to generate a reference voltage signal by taking the first direct current voltage signal and the second direct current voltage signal as input signals, output the reference voltage signal to the load; wherein a voltage value of the reference voltage signal is smaller than a voltage value of the first direct current voltage signal and is greater than a voltage value of the second direct current voltage signal.
