Mainboard power supply voltage control device and server

Abstract

The invention discloses a control device for power supply voltage of a mainboard and a server. According to the scheme, the control device comprises a first power connector, a processor and N controllable switch modules which are arranged on the mainboard, the N controllable switch modules share the first power supply connector, and the processor controls the controllable switch module corresponding to the board card to be switched on when determining the board card inserted into the first power supply connector so as to provide corresponding power supply voltage for the board card. Compared with the prior art, the device has the advantages that the power connectors on the mainboard are shared when the mainboard supplies power to board cards with different power supply voltage requirements, the number of the power connectors on the mainboard, the cost consumed by more power connectors and the PCB space, occupied by the power connectors, of the mainboard are reduced, and the power density of a server where the mainboard is located is improved; Meanwhile, the probability of wrong connection between the board card and the power supply connector on the mainboard is reduced, so that the probability that the board card cannot work normally or even is burnt down is reduced.

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 ...

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
