Abstract:
1. A server rack system, comprising: a plurality of server units comprising a first set of server units, a second set of server units and a third set of server units; a voltage converter receiving a three-phase alternating current (AC) power signal and converting the three-phase AC power signal into a first single-phase power signal, a second single-phase power signal and a third single-phase power signal, wherein the phase difference between any two of the first to the third single-phase power signals is 120 degrees; and a first set of power supply circuits, a second set of power supply circuits and a third set of power supply circuits respectively generating a first direct current (DC) power signal according to the first single-phase power signal, a second DC power signal according to the second single-phase power signal, and a third DC power signal according to the third single-phase power signal; wherein, the first set of server units is powered by the first DC power signal, the second set of server units is powered by the second DC power signal, and the third set of server units is powered by the third DC power signal; wherein each of the first to the third sets of power supply circuits comprises: N power supply circuits providing a power supply output signal to drive the corresponding first to third sets of server units, wherein N is a natural number; and at least one redundant power supply circuit replacing the power supply operation of the N power supply circuits when any of the power supply circuits operates abnormally.
