Embodiment Construction
[0044] figure 2 It is a schematic structural diagram of a power supply device for a power conversion module provided by an embodiment of the present invention. Such as figure 2 As shown, the power conversion module includes a detection switching unit 21 and a conversion unit 22 . The detection switch unit is connected with the conversion unit, and the output terminal of the conversion unit can be connected with the load, so as to supply power to the load.
[0045] The detection switching unit is also connected to the output end of the first AC power supply and the output end of the second AC power supply respectively. The detection switch unit has two input terminals, one input terminal is connected with the output terminal of the first AC power supply, and the other input terminal is connected with the output terminal of the second AC power supply. If one of the two AC power sources connected to the power conversion module works normally, the power conversion module can ...

The embodiment of the invention provides a power supply device and a power source control method. The power supply device comprises (N+m) power source conversion modules, wherein the N power source conversion modules are main power source conversion modules; each power source conversion module comprises a detection switching unit and a conversion unit; the detection switching units are connected with an output end of a first AC power source and an output end of a second AC power source, the detection switching units are configured to monitor the working state of the first AC power source and the working state of the second AC power source, close a channel between one power source in the normal working state in the first AC power source and the second AC power source and the conversion units and cut off a channel between the other power source in the first AC power source and the second AC power source and the conversion units; the conversion units are configured to convert a voltage output by the power source in the closed channel of the detection switching unit to a direct voltage required by a load. According to the embodiment of the invention, the number of the power source conversion modules in the power supply device is reduced.
Description
technical field [0001] Embodiments of the present invention relate to electronic technology, and in particular to a power conversion module, a power supply device and a power supply method. Background technique [0002] Typical communication equipment and information and communication technology (Information Communication Technology, ICT for short) equipment include a power supply device, a service board, and a cooling fan. Among them, the power supply device is responsible for receiving one or more power inputs from outside the device, and converting the power input from the outside of the device into power available for loads (including service boards, cooling fans, etc.) in the device. [0003] Such as figure 1 As shown, when N lines of power are input to the power supply device, N power conversion modules need to be installed in the power supply device, and each power conversion module is connected to one power supply, that is, N power sources need to have N power conve...
