Abstract
A cooling system of a server with an AC power source and a DC power source includes an AC input subsystem, a DC input subsystem, and a driving control subsystem. The AC input subsystem receives an external AC power source and provides a first DC voltage and a second DC voltage. The DC input subsystem receives an external DC power source and provides a third DC voltage and a fourth DC voltage. When the external AC power source normally works, the driving control subsystem controls the first DC voltage and the second DC voltage to supply a high-voltage cooling apparatus and a low-voltage cooling apparatus, respectively. When the external DC power source normally works, the driving control subsystem controls the fourth DC voltage and the third DC voltage to supply the high-voltage cooling apparatus and the low-voltage cooling apparatus, respectively.
