How much does a vehicle converter cost?(2)
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 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.
The high-voltage DC power supply for electrostatic precipitator has been developed in China. The commercial power is rectified into DC, and the full-bridge zero-current switch series resonant inverter circuit is used to invert the DC voltage to a high-frequency voltage, which is then boosted by a high-frequency transformer, and finally rectified. for DC high voltage. Under the condition of resistive load, the output DC voltage reaches 55kV, the current reaches 15mA, and the operating frequency is 25.6kHz.
It's not that expensive is good! But it depends on the specific use occasion. Only high-voltage occasions are recommended to use this 24V input power supply. Ordinary home circuits or enterprise circuits can use ordinary 24 v 24V input power supply supplies!
In addition, the situation in the current market is also very different. The price of the vehicle converter fluctuated to a certain extent. If you search online, you will find cheaper ones that cost more than ten yuan, but it is not recommended to choose this kind of excessive Inexpensive power modules, because the overall quality of this product is difficult to say, it is recommended that you choose tens of dollars, or 200-300 dollars. This kind of comprehensive technology and various aspects will also be better, so When purchasing, you should also look at the certification of the manufacturer. If a manufacturer's qualifications meet the requirements in all aspects, continue to choose. If the requirements are not met, do not blindly buy a power module.
