A control device and server for a power supply voltage of a motherboard

Abstract

The application discloses a control device and a server for the power supply voltage of a mainboard. The solution includes a first power connector, a processor, and N controllable switch modules arranged on the mainboard; the N controllable switch modules share the first power supply connector, when the processor determines the board inserted into the first power connector, the processor controls the controllable switch module corresponding to the board to be turned on, so as to provide the corresponding power supply voltage for the board. Compared with the prior art, the device realizes the sharing of power connectors on the main board when the main board supplies power to boards with different power supply voltage requirements, reducing the number of power connectors on the main board and the cost of more power connectors The PCB space occupied by the main board and the power connector improves the power density of the server where the main board is located; at the same time, it also reduces the probability of wrong connection between the board and the power connector on the main board, thereby reducing the failure of the board to work normally, or even burning The probability.

Description

technical field [0001] The invention relates to the technical field of voltage control, in particular to a control device and a server for the power supply voltage of a motherboard. Background technique [0002] In the prior art, the mainboard of the server is usually equipped with different boards in different configurations. Both the mainboard and the boards are provided with power connectors. connector so that the power supply on the motherboard supplies power to the board through the connected power connector. When multiple boards require the same power supply voltage, they usually share the power connector on the motherboard; when multiple boards require different power supply voltages, they usually set different power connectors on the motherboard to meet different configuration The power supply voltage requirements of the corresponding board, so a large number of power connectors are usually seen on the existing motherboard, and these power connectors occupy a large ...

AI Technical Summary

Problems solved by technology

When multiple boards require the same power supply voltage, they usually share the power connector on the motherboard; when multiple boards require different power supply voltages, they usually set different power connectors on the motherboard to meet different configuration The power supply voltage requirements of the corresponding board, so a large number of power connectors are usually seen on the existing motherboard, and these power connectors occupy a large part of the PCB (Printed Circuit Board, printed circuit board) on the motherboard. ) space, which limits the improvement of the power density of the server where the motherboard is located and increases the cost of the server, and also increases the probability of wrong connection between the power connector of the board and the power connector of the motherboard, which may cause the board to fail to work normally, or even burn
