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.

Polyurethane has been used in China for a period of time, but due to its high hardness, inconvenient maintenance, and the price reduction of silicone rubber, the cost performance of polyurethane is not high.

Special attention should be paid to the thermal conductivity related to thermal design. Generally, a thermal conductivity of 0.4W/M•K is defined as high thermal conductivity, and greater than 1 is defined as extremely high thermal conductivity.
