Embodiment Construction

[0027] Some certification agencies divide the conversion efficiency of power modules into multiple levels, and differentiate power products with different conversion efficiencies by certifying different levels. For example, the conversion efficiency grades of power modules can be divided into bronze, silver, gold, platinum, titanium, etc. from low to high. figure 1 It is a schematic diagram of the conversion efficiency curve of a gold / platinum level power module, such as figure 1 As shown, within the normal load range of the IT equipment, that is, within the load ratio range of 5% to 30%, the conversion efficiency of the power module cannot reach the highest conversion efficiency. However, if the conversion efficiency of the power supply is only increased by increasing the load ratio of the power supply, the IT equipment will not have redundant power distribution, which will affect the reliability of the IT equipment. Therefore, it is necessary to improve the conversion effic...

Abstract

The invention provides a power supply module. The power supply module comprises a control module and a power conversion module, wherein the control module is connected with the power conversion module; the power conversion module consists of a plurality of power conversion submodules which are connected in parallel; and the control module is used for controlling switch-off and switch-on of the power conversion submodules. According to the power supply module, the integral power conversion module is disassembled into the power conversion submodules with low power, thus, the load ratio of the power supply module is maintained in a load ratio range corresponding to the highest power conversion efficiency, and therefore, it can be ensured that the conversion efficiency of the power supply module is always maintained at the highest conversion efficiency. Further, redundant power distribution of IT equipment can become N+N redundancy from the original 1+1 redundancy, and therefore, the reliability of the power supply module is further improved.

Description

technical field [0001] The present application relates to electronic technology, in particular to a power supply module. Background technique [0002] With the continuous development of the Internet, the power consumption of Information Technology (IT) equipment applied to the Internet is gradually increasing, and energy saving and emission reduction have become an important issue in the operation and maintenance of IT equipment. Most of the current IT equipment power supply mode adopts 1+1 or N+N redundant power distribution mode. In the actual operation of IT equipment, the resource occupancy rate of the server is mostly between 10% and 60%. Said that its loading ratio is between 5% and 30%. In this case, the conversion efficiency of the power module is low. However, if the conversion efficiency of the power supply is only increased by increasing the load ratio of the power supply, the IT equipment will not have redundant power distribution, which will affect the reliabi...
