Why should the boost/buck voltage power supply for vehicle air conditioning be tested for aging(2)

●The design is simple. Power is available with just one power module, with a few discrete components. ● Shorten the development cycle. The module power supply generally has a variety of input and output options. Users can also repeatedly stack or cross stack to form a building block combined power supply to achieve multiple input and output, which greatly reduces the prototype development time.
●Change is flexible. If the product design needs to be changed, simply convert or parallel another suitable power module.

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.

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.
