Power supply for double-mainboard computer

Abstract

The invention discloses a power source for supplying power to a double-mainboard computer. The structure of the power source consists of computer power supplies, two computer main boards, two field-effect transistors (Q1 and Q2), and power controllers. The computer power supplies are serially connected with the field-effect transistors (Q1 and Q2) and used for supplying power to the computer main boards; the communication or closing of each of filed-effect transistors is controlled by the power controller; the connection manner for each pin of the field-effect transistors (Q1 and Q2) is that source electrodes (S) of the Q1 and the Q2 are in parallel connection with the computer power supply, drain electrodes (D) are respectively connected with the main board 1 and the main board 2, and grid electrodes (G) are respectively connected with the power controller 1 and the power controller 2. Compared with the prior art, the art adopted by invention is characterized in that the double-mainboard system has higher performance, and two sets of systems can back up each other and mutually tolerate faults so that the important data can not be lost and the key business can not be interrupted even though one set of system is broken. Therefore, the double-mainboard system possesses the widespread market development prospect and the application value.

Description

technical field [0001] The invention relates to the technical field of computer power supplies, and specifically provides a power supply for a dual-mainboard computer. technical background [0002] Assembling two sets of system mainboards in a computer server case serves as mutual backup and mutual fault tolerance. It goes without saying that there is always a possibility of server damage. A single server chassis in an ordinary server has only one system motherboard. Once a failure or damage occurs, data loss or business interruption will inevitably result. [0003] Since the dual mainboard system has two sets of mainboards, the existing technology mostly uses a "one-to-one" power supply method, that is, one power supply only supplies power to one mainboard. This power supply method is the simplest and most reliable, but it occupies more space in the chassis.

It goes without saying that there is always a possibility of server damage. There is only one system motherboard in a single server chassis in an ordinary server. Once a failure or damage occurs, it will inevitably cause data loss or business interruption.

[0003] Due to the fact that the dual-mainboard system has two sets of mainboards, the existing technology mostly uses a "one-to-one" power supply method, that is, one power supply only supplies power to one mainboard. This power supply method is the simplest and most reliable, but it occupies more chassis space.
