电源模块是一种可以直接贴装在印刷电路板上的电源转换器，按变换方式一般分为AC转DC或DC转DC。随着科技的发展，电源体积趋向模块化和小型化，于是出现了电源模块。

其集成度最高，将开关电源的主要电路集成在芯片中，可以实现宽频调制、隔离及多种保护等功能。

常见的基本原理由以下部分组成，输入整流滤波器，包含整流桥和输入滤波电容。单片开关电源，包括功率开关管、控制器及MOSFET。还有高频变压器、漏级钳位保护电路、光耦反馈电路、输出整流滤波器、偏置电路等部分组成。

The power module is a power converter that can be mounted directly on the printed circuit board, which is generally divided into AC to DC or DC to DC according to the conversion method. With the development of science and technology, the volume of power supplies tends to be modular and miniaturized, so there is a power module.

The main circuit of the switching power supply is integrated in the chip, which can realize the functions of broadband modulation, isolation and a variety of protection.

The common basic principle consists of the following parts, the input rectifier filter, including the rectifier bridge and the input filter capacitor. Monolithic switching power supply, including power switching tube, controller and MOSFET. There are also high frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts.
