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

(DC/DC) converter
The DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the stepless speed change and control of trolleybuses, subway trains, and electric vehicles. Responsive performance, and at the same time receive the effect of saving power. Replacing the varistor with a DC chopper can save power by (20~30)%. The DC chopper can not only play the role of voltage regulation (switching power supply), but also can effectively suppress the harmonic current noise on the grid side.

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?

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 LED advertising screen 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.
