Why should the boost/buck voltage power supply for vehicle air conditioning be tested for aging(2)
Before the dc switching power supply supply leaves the factory, it often goes through rigorous tests, including high and low temperature tests. The boost/buck voltage power supply for vehicle air conditioning, which has been tested at high and low temperatures, can ensure the quality of the goods, reduce the probability of abnormality during the whole application process, and increase the service life. Although the dc switching power supply supply just went out of the production line can be applied immediately, many of the products were found useless when they were in the hands of customers. This is because in the process of processing, only simple plug in detection is performed, and the plug in detection of long-term different natural environment is not performed.
Most of the common faults of dc switching power supply supply products occur in the early and middle late stages, and the manufacturer cannot accurately manipulate the middle and late stages, so only the early stage can be manipulated. Before the goods are handed over to the customer, the problem should be eliminated before delivery.
●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.
The key methods of dc switching power supply supply embrittlement include load embrittlement at normal warm temperature and high and low temperature test with high temperature plug in. The common method is high temperature embrittlement. According to the high temperature embrittlement, the shortcomings or poor quality of commodity components can be exposed, thereby improving the reliability and credibility of the commodity.
