Abstract
The power supply device includes an AC-DC conversion unit configured to provide a source DC voltage signal; a first DC-DC conversion unit configured to generate a first DC voltage signal and a second DC voltage signal according to the source DC voltage signal, output the first DC voltage signal to the load through a first output interface and output the second DC 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 DC voltage signal and the second DC 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 DC voltage signal and is greater than a voltage value of the second DC voltage signal.
