With the global emphasis on environmental protection and sustainable development, the new energy vehicle (NEV) industry has entered a period of rapid growth. As the “heart” of the on-board power supply system for NEVs, DC/DC converters are experiencing rapid demand growth. In 2024, the market size of NEV DC/DC converters in China reached 22.067 billion yuan, and it is estimated that this figure will rise to 48.323 billion yuan by 2028.
Taking “overshoot and recovery time” as an example, DC/DC converters are required to have an output voltage overshoot of no more than 10% and a recovery time of no more than 5ms when the load changes abruptly. Therefore, high requirements are imposed on the dynamic response performance of electronic loads for testing purposes; typically, the current rise slope should be in the range of A/μs (amps per microsecond).

WORKING DAILY, WITH GOALS IN MIND WILL MAKE ALL THE DIFERENCE WHEN PUSH COMES TO SHOVE
Before DC/DC converters leave the factory, manufacturers usually conduct aging tests, which are characterized by long test durations and high power consumption. Taking a 3.5kW DC/DC converter as an example, the electricity cost for a single unit’s 24-hour factory aging test exceeds 80 yuan. Based on an annual shipment scale of 10,000 units, the annual electricity cost alone reaches the million-yuan level, not to mention the additional
