How much does a vehicle voltage booster cost?(1)

Now if you go to search for vehicle voltage booster, 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?

The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectification loss and line conduction loss. In the application of low voltage and high current output, the rectification loss and line conduction loss account for a larger proportion. .

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 voltage booster 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 24V input 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.
