[0003] For the DC-to-DC power module, it is necessary to test its functional indicators before lea...

AI Technical Summary

Problems solved by technology

[0003] For the DC-to-DC power supply module, its functional indicators need to be tested before leaving the factory. The traditional method mainly obtains the results through manual measurement. The test equipment is complicated. According to different parameter indicators, the test circuit methods are also different, which ultimately leads to low test efficiency.

Moreover, the traditional test indicators are simple, only the output voltage, output current, and efficiency are tested, and the evaluation indicators for the DC-to-DC power module are not comprehensive enough.
