What does a DC conversion power supply look like?(5)

In the early 1980s, the research on the distributed high frequency switching power supply system basically focused on the research of the converter parallel technology. In the mid-to-late 1980s, with the rapid development of high-frequency power conversion technology, various converter topologies appeared one after another. Combined with large-scale integrated circuit and power component technology, it became possible to integrate small and medium power devices, thereby rapidly Promote the development of distributed high-frequency switching power supply system research. Since the late 1980s, this direction has become a research hotspot in the international power electronics field.

Regardless of how much control the product material and production process are, aging needs to be checked. Because the incoming inspection of electronic components and transformers is difficult to control, the quality stability of this batch of power supplies and whether the materials are detected to have potential safety hazards can only be detected through aging and high-temperature sampling of the entire batch of power supplies.
