How much does a boost/buck voltage power supply for vehicle air conditioning cost?(1)

The distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.

Now if you go to search for boost/buck voltage Marine boost power supply for vehicle air conditioning, 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   boost/buck voltage Marine boost power supply for vehicle air conditioning 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 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.
