Switching power supply protection method and system based on switching power supply automatic test platform

Abstract

The invention provides a switching power supply protection method and system based on a switching power supply automatic test platform. The switching power supply automatic test platform comprises a group of test instruments for testing the performance of a switching power supply. The switching power supply protection method comprises a step of creating multithreading, and obtaining the current actual test data of each of the above test instruments, a step of comparing each obtained actual test data with a corresponding numerical range and then judging whether to control the above switching power supply to loss power or not. The power supply protection system comprises a switching power supply performance test data collection unit, a storage unit and a control unit, the multithreading is created, and the current actual test data of each test instrument is obtained. The current obtained actual test data and the corresponding preset numerical range are compared, and then whether the above switching power is controlled to loss power is judged. According to the method and the system, the breakdown of a test power supply and a test instrument in an automatic test process can be prevented.

Description

technical field [0001] The invention relates to the field of switching power supply testing, in particular to a switching power supply protection method and system based on a switching power supply automatic testing platform. Background technique [0002] With the rapid development of the server industry, higher requirements are placed on the performance of switching power supplies. Due to the large number of test instruments used in the power supply test and the relatively complicated test content, in the single power supply test, an automated test platform (that is, a switching power supply automated test platform) is usually used. [0003] The automated test platform is built by AC / DC power supply, DC electronic load, oscilloscope, signal generator, frequency response analyzer, digital multimeter and other test equipment that can be connected by GPIB communication cable, and is used to test the different performances of switching power supplies . [0004] The automatic ...

AI Technical Summary

Problems solved by technology

[0004] The automatic test platform for switching power supply takes a short time, and the measurement results are accurate and consistent. However, the existing technology is not strong enough to monitor the abnormality of the power supply test. If the switching power supply fails, but the test continues, it is easy to destroy the switching power supply being tested, or even destroy the testing equipment used in the current switching power supply automation test platform, thereby increasing the cost of testing and production
