Problems solved by technology

[0003] In the process of the above performance test, because the load will consume electric energy, it will cause energy loss and large cost waste
In addition, aging a DC / DC conversion module requires a high-voltage DC source. To achieve simultaneous aging of multiple DC / DC conversion modules, multiple high-voltage DC sources are required, which leads to high costs. If multiple High-voltage DC source, the aging cycle is too long and the production efficiency is low

Abstract

The present disclosure relates to a DC / DC conversion module testing system and a testing method thereof, capable of performing performance tests on multiple DC / DC conversion modules simultaneously, saving time and required equipment. The test system includes a first high-voltage DC source, a second high-voltage DC source, and 2N+1 DC / DC conversion modules, and the 2N+1 DC / DC conversion modules are connected in series with the first high-voltage DC source, The second high voltage direct current source is connected in series again, wherein N is a positive integer.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a test system and a test method for a DC / DC conversion module. Background technique [0002] At present, the performance of DC / DC conversion modules is usually tested through power aging tests, and in power aging tests, most of the DC / DC conversion modules are connected with high-voltage DC sources and loads, such as figure 1 shown. [0003] During the above performance testing process, since the load consumes electric energy, energy loss and large waste of cost will be caused. In addition, aging a DC / DC conversion module requires a high-voltage DC source. To achieve simultaneous aging of multiple DC / DC conversion modules, multiple high-voltage DC sources are required, which leads to high costs. If multiple High-voltage DC source, the aging cycle is too long and the production efficiency is low. Contents of the invention [0004] The purpose of the present ...
