Embodiment 1

[0039] see figure 1 , figure 1 It is a schematic structural diagram of an AVSbus power supply test system provided in the embodiment of the present application. Depend on figure 1 It can be seen that the test system of the AVSbus power supply in this embodiment mainly includes: a load module, an AVSbus communication module and a host computer control module. Wherein, the load module is used to extract load current from the output end of the AVSbus power supply, and the load current is used to simulate the working current of the load chip. The AVSbus communication module is used to obtain the instructions of the upper computer control module, translate the instructions of the upper computer control module into AVSbus instructions, and simulate the master device of the AVSbus power supply. The master device of the AVSbus power supply is the load chip, and the slave device of the AVSbus power supply is the power supply Controller, AVSbus command includes: set voltage command. ...

Embodiment 2

[0043] exist Figure 1-Figure 3 On the basis of the illustrated embodiment see Figure 4 , Figure 4 It is a schematic flowchart of an AVSbus power supply testing method provided in the embodiment of the present application. Depend on Figure 4 As can be seen, the test method of the AVSbus power supply in the present embodiment comprises the following processes:

[0044] S1: According to the acquired command, simulate the master device of the AVSbus power supply, and send the AVSbus command to the AVSbus power supply.

[0045] S2: Draw the current load current from the output terminal of the AVSbus power supply. Among them, the load current is used to simulate the working current of the load chip.

[0046] In this embodiment, the method for extracting the current load current from the output end of the AVSbus power supply is: using a load module to extract the current load current from the output end of the AVSbus power supply. Among them, the load module includes: a sig...

Abstract

The invention discloses a system and a method for testing an AVSbus power supply. The system comprises a load module, an AVSbus communication module and an upper computer control module. The method comprises the steps that a main device of the AVSbus power supply is simulated according to an obtained instruction, and an AVSbus instruction is sent to the AVSbus power supply; the current load current is extracted from the output end of the AVSbus power supply; the AVSbus power supply adjusts the output current or the output voltage according to the obtained AVSbus instruction and the current load current; and finally, according to the output current or the output voltage of the AVSbus power supply, the input state and the output state of the AVSbus power supply are acquired. According to the invention, the AVSbus power supply can be tested and verified more completely, and the accuracy of the test result can be improved.

Description

technical field [0001] The present application relates to the technical field of server power supply testing, in particular to an AVSbus power supply testing system and method. Background technique [0002] With the development of Internet of Things technology, in terms of the infrastructure power supply market, servers and data centers have put forward higher requirements on the performance of power supplies. The power supply is developing towards the digital power supply, especially the digital multi-phase controller. Among them, the AVSbus power supply is a more efficient and low-cost power supply that meets market demand. In order to improve the stability of the whole system and ensure the performance of the AVSbus power supply, it is necessary to test the AVSbus power supply. [0003] At present, the test method of AVSbus power supply is usually to use the AVSbus power supply as a common power supply, use an electronic load to perform a load test, and confirm the perf...
