How much does a vehicle converter cost?(1)

Now if you go to search for vehicle converter, you will find that the price difference is very big. The cheap ones are more than ten yuan, and the more expensive ones are more than 1,000 yuan. Why is the price difference between the cheap and the expensive so big? What are the main differences?

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,

There is a big difference in price between cheap and expensive. In fact, this is mainly because it is used in different occasions. Thousands of dollars are generally used in  vehicle converter systems. This kind of power module has high requirements on performance, parameters, life and other aspects, and the price will be more expensive, and this kind of power module is a high-frequency voltage switching Marine boost/buck voltage power supply with multiple independent outputs, which is very important to the production process, etc. The requirements in all aspects are also relatively high, so this will be more expensive.
