[0029] Please refer to Figures 1 to 2 The utility model provides a kind of server double-input power supply system, comprising:

[0030] The first power terminal 1 has an input end for connecting a first AC power supply and an output end for connecting a server, and is configured to output the first AC power supply to the first server power module 5 to supply power to the server.

[0031] The power processing module 2 has an input end for connecting a second AC power supply and an output end for connecting a server, and is configured to output the AC power supply to the second server power module 6 or output a stored backup power supply to the second server power module 6 to supply power to the server.

[0032] The switch module 3 is connected in series between the output end of the power processing module 2 and the second server power module 6.

[0033] The monitoring module 4 has a detection end electrically connected to the first power terminal 1 and a control end electrically connected to a controlled end of the switch module 3, and is configured to monitor the AC power supply connected to the first power terminal 1 and, when detecting an abnormality in the AC power supply connected to the first power terminal 1, control the switch module 3 to connect the output end of the power processing module to the server to control the power processing module 2 to supply power to the second server power module 6.

[0034] In the embodiment, the first AC power supply can be provided by a first commercial power supply or a power supply provided by another AC generator, the second AC power supply can be provided by a second commercial power supply or a power supply provided by another AC generator, the power processing module 2 can be implemented by a UPS power module, a DC redundant power module, an EPS specification power module, a DPS specification power module, etc., and has a battery module arranged therein to provide a backup power supply, the switch module 3 can be an STS switch, and the monitoring module 4 can be a circuit for detecting the waveforms of the first AC power supply and the second AC power supply, which is used in combination with a signal acquisition circuit, a signal conditioning circuit, an analog-to-digital conversion circuit (ADC), and a data processing and analysis circuit, to determine whether the first AC power supply and the second AC power supply are abnormal according to a set fixed abnormal voltage waveform, or is used in combination with a voltage divider network and a main controller (such as an MCU chip or a SOC chip) to detect the voltages of the first AC power supply and the second AC power supply and determine whether the first AC power supply and the second AC power supply are abnormal according to a set fixed abnormal voltage threshold, or is used in combination with an electronic counter, a frequency counter, and a single-chip microcomputer (such as a pic16f1823 chip) to detect the frequencies of the first AC power supply and the second AC power supply and determine whether the first AC power supply and the second AC power supply are abnormal according to a set fixed abnormal voltage frequency threshold.

[0035] Specifically, the switching control unit such as the BMS management system or the UPS system in the power processing module 2 is set to a hot backup state, and when the monitoring module 4 detects that the first AC power output from the first power terminal 1 to the first server power module 5 is abnormal, the switching module 3 is controlled to be turned on, and the power processing module 2 in the hot backup state outputs the second AC power to the second server power module 6, or when the second AC power is abnormal, the stored backup power is output to supply power to the server. It is worth mentioning that when the power processing module is in a hot backup state and the switching module is an STS switch, if the switching module is closed at this time (i.e., the server is powered by the first server power module), the power processing module 2 can be in an idle state without output to reduce energy consumption, and the server power is supplied directly by the mains at this time to efficiently use the mains. On this basis, further, since the output terminals of the first server power module 5 and the second server power module 6 are in a parallel relationship when supplying power to the server in general, the continuous operation of the server is naturally ensured when the second server power module 6 outputs. In this way, the second server power module 6 can be set to a cold backup state, and when receiving the power output by the power processing module 2, the second server power module 6 can be immediately awakened to enter the working state, thereby reducing the no-load loss of the power processing module 2 when it is not started.

[0036] In this embodiment, the internal voltage of the first server power module and the second server power module can be converted by a voltage management chip, or the current can be converted by a current rectification chip to supply power to the server; the first server power module 5 and the second server power module 6 can be set to have priority, and the first server power module 5 can supply power preferentially when the power supply is normal, and a large-capacity capacitor can be arranged in the first server power module 5 to ensure stable power output when the power supply fluctuates. When the first server power module 5 fails or the voltage is unstable, the system will automatically switch to the second server power module 6 to supply power to ensure the continuous operation of the server. In this way, when the first AC power supply is restored, the second server power supply can be switched to the first server power module 5 with sufficient time.

[0037] In summary, the technical solution of the embodiment can more efficiently utilize the direct mains power supply with low energy consumption rate, and effectively reduce energy consumption.
