一、电源模块的作用
电源模块的作用就是电压的转换，它可以将交流或直流电变换成你所需要的交流或直流电。如:将市电220V交流电(AC)转换成5V直流电(DC)，因为交流220V的电是高压电，而电子产品是低压供电的，这就需要一个转换装置 ，将交流220V的电压转换成低压。再比如在机动车里有时需要转换成220V交流电来使用，那么这会就成了低压转高压了，因为机动车的电压一般都比较低。简而言之就是类似手机充电器-样， 你的手机没电了,要插电或充电才能正常使用，但是你不能直接接220V使用，因为这样手机就会烧毁，因此就需要一个专门的转换装置来转换成手机所需的电压。
二、如何选择合适的电源模块
1、电路设计原理和工艺
电路原理的好坏分辨通常只能从专业角度着手。现阶段电源模块大体可分为裸板和灌封两种，裸板可以根据直观的方式，如电子元器件的布局合理整齐有序、大方、有序、焊点亮净挺拔。而灌封式模块，就没法查看内部的情况，但是由于不外露，在安全性和性能指标层面要好很多。焊接I艺可包括手工焊接与波峰焊工艺，机械化生产的波峰焊工艺品质要优于手工焊接。

1、 The function of the power module
The function of the power module is to convert voltage, which can convert AC or DC power into the AC or DC power you need. For example, converting 220V AC from mains power to 5V DC, as 220V AC is high-voltage and electronic products are low-voltage powered, requires a conversion device to convert 220V AC voltage into low-voltage. For example, in motor vehicles, sometimes it is necessary to convert to 220V AC for use, which can become a low voltage to high voltage conversion, because the voltage of motor vehicles is generally relatively low. In short, it is similar to a mobile phone charger. Your phone runs out of battery and needs to be plugged in or charged to function properly. However, you cannot directly connect it to 220V, as this will cause the phone to burn out. Therefore, a specialized conversion device is needed to convert it to the voltage required for the phone.
2、 How to choose the appropriate power module
1. Circuit design principles and processes
The distinction between good and bad circuit principles can usually only be approached from a professional perspective. At present, power modules can be generally divided into two types: bare board and encapsulated. The bare board can be arranged in an intuitive manner, such as the layout of electronic components being reasonable, orderly, generous, and orderly, with bright and straight solder joints. The encapsulated module cannot check the internal situation, but due to its non exposure, it is much better in terms of safety and performance indicators. The welding process can include manual welding and wave soldering, and the quality of the wave soldering process produced by mechanization is better than that of manual welding.
