What are the advantages of DC module power supply?(2)
(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;
(2)DC module power supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
(3) The technology is relatively simple, and it is easy to meet the relevant requirements;
(4) DC module power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
(6)DC module power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;
The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.
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,
In many fields, switching power supply modules play a role that cannot be ignored and are very important.
