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。
2、芯片的元器件
电源的核心就是IC,它犹如电源的大脑一样，IC的好坏直接影响着电源的各项参数。
3、压器元器件
决定电源的功率、耐温等则是变压器。变压器负责完成交流电直流电，能量超载就会饱和炸机

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.
2. Chip components
The core of a power supply is the IC, which is like the brain of a power supply. The quality of the IC directly affects the various parameters of the power supply.
3. Voltage components
The transformer determines the power and temperature resistance of the power supply. The transformer is responsible for completing AC and DC power, and energy overload will saturate and explode the machine
