How much does a vehicle converter cost?(1)
Diode loss
Diode rectification is used in traditional rectification, and Schottky diode rectification is generally used under low voltage output conditions. Compared with other rectifier diodes, Schottky diodes have the advantages of faster switching speed and lower forward voltage, but Schottky diodes The forward voltage drop of the diode is related to the size of the rectified output current. The larger the rectified output current is, the greater the forward voltage drop, which may be as high as 0.5~0.6V or more, and the reverse leakage current of the Schottky diode is larger. .
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?
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 48V 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.
