How much does a vehicle cost?(3)


DC Module power

module combination
(1) Parallel expansion. Connecting the output terminals of the same module in parallel can enhance the output capability, but the output voltage of the parallel modules should be adjusted to be consistent to ensure relative current sharing and avoid unnecessary oscillations. For modules with large current output, the lead resistance can also be carefully designed to achieve the effect of current sharing. The number of modules connected in parallel in this way should not exceed 2. At the same time, if one of the module outputs is faulty, the entire system will not work properly. The parallel expansion connection circuit RL is the load.

In addition, the situation in the current market is also very different. The price of the vehicle 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.
