Problems solved by technology

[0003] But as more devices are deployed, more and more power supplies are required for redundancy in this way, leading to higher costs
So a single power supply module with dual input power supply appeared. Using such a module can save up to half of the modules for the system, thereby reducing the cost of deployment in the computer room, but it also brings some problems. For example, the computer room uses mains redundancy to ensure For the normal operation of the data center, the use of dual input power supplies will cause serious load imbalance between the two mains.

Embodiment 1

[0025] A cabinet-type three-phase dual-input load-balanced power supply system, the power supply frame of the power supply system includes a control module, a PSU slot, a power supply input distribution circuit board, and an output circuit, wherein:

[0026] The PSU power supply is connected to the power supply input distribution circuit board, output circuit and control module by inserting into the PSU slot of the power supply frame;

[0027] AC power is input to the power supply frame, and the power supply frame supplies power to the PSU through the power supply input distribution circuit board, and the PSU outputs the voltage required by the rack server, which is sent to the rack server by the output circuit;

[0028] The control module controls and monitors the state of the input and output, and can manage the state of the PSU.

Embodiment 2

[0030] On the basis of Embodiment 1, the wiring inside the power supply frame described in this embodiment uses the phase-to-phase voltage as the input of the PSU.

[0031] Since the input voltage range of domestic PSUs is generally between 180V-260V, the three-phase 120V electricity in the United States cannot directly supply power to PSUs, but the phase-to-phase voltage is 208V, which is within the input voltage range of domestic PSUs. Routing, using the phase-to-phase voltage as the input of the PSU, can achieve the purpose of using the domestic PSU abroad. This method is conducive to reducing the cost of research and development, improving the speed of product development, and has practical application value.

Embodiment 3

[0033] On the basis of Embodiment 1 or 2, since the power supply is a dual-input power supply, there is no load on the input terminal as a backup during normal operation, and it will work only when an abnormality occurs. Therefore, once there is a problem under no load for a long time, it cannot Switching occurs when the power supply is abnormal, thus affecting the normal operation of the cabinet. In order to solve this problem in this embodiment, the power supply system is provided with a dual-input switching detection function module, which is realized after the primary test of the power supply, that is, after the mains power of the switching power supply is converted to high voltage, and only a part of the traditional power supply is used for the primary test circuit, and the dual-input The power supply has two parts, the primary test circuit, which are connected in parallel, and then collected to the secondary side for DC high-voltage step-down to the 12V voltage required b...

Abstract

The invention discloses a cabinet-type three-phase dual-input load balancing power supply system. The power supply frame of the power supply system includes a control module, a PSU slot, a power supply input distribution circuit board and an output circuit. The PSU power supply module is inserted into the power supply frame. The PSU slot is connected to the power supply input distribution circuit board, output circuit and control module; AC power is input to the power supply frame, the power supply frame supplies power to the PSU through the power supply input distribution circuit board, and the PSU outputs the voltage required by the rack server. It is delivered to the rack server by the output circuit; the control module controls and monitors the status of the input and output, and can manage the status of the PSU. The invention is applied to the smart rack of the cabinet-type server, which can realize the three-phase two-way power supply load balance in the computer room, and at the same time, the power supply for the whole cabinet server is more stable, the cost is lower, the occupied space is smaller, and the number of server nodes that can be supported is more. Advantages make the product more competitive in the market.

Description

technical field [0001] The invention relates to the technical field of server cabinet power supplies, in particular to a cabinet-type three-phase dual-input load-balanced power supply system. Background technique [0002] With the birth and continuous development of the Internet, the demand and sharing of information from all walks of life in the world is also increasing. The number and scale of data centers that provide information services for various computers are constantly expanding. The demand for servers is also constantly increasing. Traditional servers use redundant power supply through the number of power modules, that is, use twice the number of cabinet power supplies to form an N+N redundant mode, which has load balancing and high efficiency. The advantages of stable power supply are currently used in most computer rooms. [0003] But as more devices are deployed, more and more power supplies are required for redundancy in this way, leading to higher costs. So...
