Abstract:
1. A cooling system of a server with an AC power source and a DC power source electrically connected to an external AC power source and an external DC power source to drive at least one high-voltage cooling apparatus and at least one low-voltage cooling apparatus, the cooling system comprising: an AC input subsystem receiving the external AC power source to provide a first DC voltage and a second DC voltage, wherein the second DC voltage is provided by stepping down the first DC voltage; a DC input subsystem receiving the external DC power source to provide a third DC voltage and a fourth DC voltage, wherein the fourth DC voltage is provided by stepping up the third DC voltage; and a driving control subsystem electrically connected to the AC input subsystem and the DC input subsystem to receive the first DC voltage, the second DC voltage, the third DC voltage, and the fourth DC voltage; wherein the driving control subsystem controls the first DC voltage and the second DC voltage to respectively supply power to the high-voltage cooling apparatus and the low-voltage cooling apparatus when the external AC power source normally supplies power; the driving control subsystem controls the fourth DC voltage and the third DC voltage to respectively supply power to the high-voltage cooling apparatus and the low-voltage cooling apparatus when the external DC power source normally supplies power and the external AC power source does not normally supply power.
