[0002] As is well known, in the fields of research, development, production, and maintenance of electronic devices, the performance of switching power supplies is crucial for the stable operation of the entire system. Traditional testing methods often rely on simple instruments for single-parameter measurement, making it difficult to comprehensively and accurately evaluate the various performances of switching power supplies. Therefore, a switching power supply performance testing device has emerged. It is a professional device dedicated to comprehensively, efficiently, and accurately testing various performance indicators of switching power supplies, such as output voltage stability, current accuracy, and ripple magnitude, and can effectively ensure the quality and compatibility of switching power supplies.

[0003] Currently, a Chinese invention with the publication number: CN102495378B discloses a switching power supply testing device, which includes an insulated power supply placement board, limit guide posts, and an insulated cover plate. The limit guide posts are fixed on the power supply placement board, and the insulated cover plate is installed on the limit guide posts and can slide relative to the power supply placement board. Among them, conductive input thimbles and output thimbles are provided on the power supply placement board corresponding to the input and output ends of the switching power supply. The testing device with the above structure can avoid people contacting the energized semi-finished products during the testing process, that is, it can provide safety. In addition, the testing process is simple, easy to operate, convenient for batch detection, and there is no need to connect the input and output ends of the switching power supply one by one, greatly improving the testing efficiency.

[0004] The existing switching power supply performance testing devices have the following disadvantages when in use:

[0005] 1. When testing the performance of a switching power supply, due to the lack of a real-time switching structure for different interface devices, it is impossible to quickly switch between different interfaces in real time, reducing the flexibility of testing the performance of the switching power supply.

[0006] 2. When testing the performance of a switching power supply, due to the lack of a structure for simulating multiple environments for the environment in which the switching power supply performance is located, it is impossible to simulate various complex environments in real time, reducing the flexibility of testing the performance of the switching power supply. Summary of the Invention

[0007] The purpose of the present invention is directed to an existing switching power supply performance testing device, and its advantages are:

[0008] 1. When testing the performance of a switching power supply, due to having a real-time switching structure for different interface devices, it is possible to quickly switch between different interfaces in real time, improving the flexibility of testing the performance of the switching power supply.

[0009] 2. When testing the performance of a switching power supply, since there are various environmental simulation structures for the environment where the switching power supply is located, various complex environments can be simulated in real time, improving the flexibility during the performance test of the switching power supply.
