Loss of Magnetic Components
Transformer loss is also an important part of module switching power loss, and transformer loss mainly includes iron loss and copper loss. Iron loss refers to the high frequency loss caused by the material, shape, process structure and other related factors of the transformer, and copper loss refers to the conduction loss caused by the transformer winding circuit. In order to reduce the iron loss of the transformer, high frequency should be selected. It is a magnetic core material with good characteristics, low high frequency loss,

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.
