开关电源是应用非常广泛的一种电力电子装置。在我们生活中常见的比如电动车充电器，家用各种电器的适配器，对手机来讲就是我们说的“大头”，不常见的也就是大的方面在航空航天、军事、等方面都有应用。它能量转换效率高、体积小、重量轻、在小功率范围上开关电源已经成为主流技术，并迅速向中大功率范围上研究和应用。所以如何研究此类电源以加大其功率成为一个重要的研究方向。本文将先介绍电源的原理，分出各个模块来解析电源的原理，然后进行系统的仿真来验证原理的正确性，最后得到稳压效果。本系统主要通过硬件来实现，通过下文给出的计算方法来确定一些比如高频变压器等重要部件的参数，最终得出一个理想的开关电源。

Switching power supply is a kind of power electronic device which is widely used. The common ones in our life, such as electric car charger and adapter of various household appliances, are what we call "big head" for mobile phones, and the uncommon ones are large-scale applications in aerospace, military and other fields. Its high energy conversion efficiency, small size, light weight, in the small power range of switching power supply has become the mainstream technology, and quickly to the middle and high power range of research and application. So how to study this kind of power supply to increase its power has become an important research direction. This paper will first introduce the principle of the power supply, divided into each module to analyze the principle of the power supply, and then carry out system simulation to verify the correctness of the principle, and finally get the voltage stabilizing effect. This system is mainly realized by hardware, through the calculation method given below to determine some important components such as high-frequency transformer parameters, and finally get an ideal switching power supply.<br>
