[0079] Through the embodiments provided in this application, the purpose of providing an adaptive power supply that can automatically identify AC or DC for load devices under the condition of a single AC power supply input is achieved. For the same output jack, the output current of the DC type or current type is automatically adjusted according to the load type, thereby achieving the technical effect of improving the power supply efficiency of the device.

[0080] As an optional solution, the above-mentioned adaptive output power supply can be but is not limited to being applied in the scenario of automatically adjusting AC or DC output according to the load type in the field of power distribution technology. In this scenario, with the vigorous development of data centers, the installed capacity of data centers continues to increase, the IT devices in the cabinets also steadily increase, and their power consumption situations become more and more complex. The most basic problem among them is whether the power supply provided by this computer room (cabinet) is AC or DC? Then, the IT devices adjust the computer room on which they are installed, or adjust the power supply modules of the IT devices according to the AC / DC situation. Sometimes, it even involves a large-scale adjustment of the network wiring situation, which causes a great waste of manpower and material resources.

[0081] Using the above-mentioned adaptive output power supply, under the condition of a single AC or DC power supply input, an adaptive power supply that can automatically identify AC or DC is provided for the load. That is, for the same output jack, the output AC or DC is automatically adjusted according to the load type.

[0082] Specifically, the above-mentioned adaptive output power supply can be but is not limited to being divided into two similar structures of AC input and DC input, mainly including: air switch K, current transformer CT, voltage delay contactor KT2, current delay contactor KT1, voltage contactor KV3, rectification or inversion module, and power distribution circuit.

[0083] Optionally, in this embodiment, after the load is connected, the main circuit collects the current through the current transformer CT and passes it through the current delay relay KT1 to determine whether the load is AC or DC. The function of the auxiliary circuit is to determine whether to input the rectification or inversion module according to the type after determining whether the load is AC or DC, and use this as the final output.

[0084] For further illustration, such as Figure 3As shown, the preset current delay relay KT1 has a delay of 3 s, and the voltage delay contactor KT2 has a delay of 6 s. The input power supply is alternating current. When the load is alternating current, the current transformer CT passes alternating current. After a 3-s delay of the current delay contactor KT1, the three normally closed contacts of the current delay contactor KT1 simultaneously change from closed to open; at this time, the rectification circuit has been cut off; the load is supplied with alternating current from the main circuit. When the load is direct current, no current passes through the current transformer CT; the three normally closed contacts of the current delay contactor KT1 continue to remain closed; when 6 s is reached, the voltage delay contactor KT2 operates, and the two normally open contacts of the voltage delay contactor KT2 change from open to closed, and at the same time the voltage contactor KV3 is energized, and the two normally closed contacts of the voltage contactor KV3 change from closed to open (cutting off the alternating current); at this time, the rectification module works and outputs direct current power supply to the load.

[0085] Similarly, when the input power supply is direct current, as Figure 4 shown, the input power supply is direct current. Through the combined action of each component and the adjustment and setting of the delay parameters, when the load is direct current, the inverter circuit where the inverter is located is cut off, and the load is supplied with direct current from the main circuit. And when the load is alternating current, the inverter circuit where the inverter is located is connected and the processed alternating current power supply is output to the load.

[0086] It should be noted that the above-mentioned power supply with adaptive output automatically discriminates the type of load through the action of each component for the single input of direct current or alternating current power supply, and provides a suitable power supply for it. The load can directly access the output end of the present invention regardless of the power supply type and can operate normally.

[0087] It also should be noted that the above-mentioned power supply structure with adaptive output is simple and easy to implement; the components are easy to obtain and the cost is low; the output variability is strong: the rectifier or inverter can select a suitable output voltage range according to the demand; the scalability is strong: the circuit principle of a single output is provided; when facing a large number of demands, the function of the contactor can be realized through the PLC, and finally the application of a large number of demands is satisfied.

[0088] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
