Problems solved by technology
But there are the following problems: Although the efficiency can be improved by using better ICs and better devices, the cost of the power supply circuit is enlarged because of the different schemes adopted in this way, that is, although the efficiency is improved and the loss is reduced, the electricity bill It has been reduced, but the procurement cost has been improved, so this solution cannot fundamentally reduce the TCO (Total Cost of Ownership, total cost of ownership) of the data center, and is not economical and easy to use

The invention provides a method for designing a motherboard direct-current (DC) power supply. The method comprises the steps of acquiring output voltage under a preset load of the motherboard DC power supply; judging whether the output voltage under the preset load is higher than a preset threshold value or not; and if the output voltage under the preset load is higher than the preset threshold value, adopting primary power supply conversion, and adopting secondary power supply conversion if the output voltage under the preset load is lower than the preset threshold value. According to the method, the acquired output voltage under the preset load of the motherboard DC power supply is compared with the preset threshold value, and an adopted power supply conversion mode is finally judged, so that the efficiency of power supply conversion is increased, the loss and cost are reduced, and then, the method has usability. The invention further discloses a device for designing the motherboard DC power supply.
Description
technical field [0001] The invention relates to the technical field of DC voltage design for a complete cabinet, in particular to a method and device for designing a DC power supply for a motherboard. Background technique [0002] In the prior art, better ICs (Integrated Circuits, integrated circuits) and better devices are generally used to improve the power conversion efficiency of the DC power supply circuit to reduce losses. But there are the following problems: Although the efficiency can be improved by using better ICs and better devices, the cost of the power supply circuit is enlarged because of the different schemes adopted in this way, that is, although the efficiency is improved and the loss is reduced, the electricity bill It has been reduced, but the procurement cost has been increased. Therefore, this solution cannot fundamentally reduce the TCO (Total Cost of Ownership, total cost of ownership) of the data center, and is not economical and easy to use. Conte...
