摘　　要：根据目前主流笔记本电脑的电源适配器使用特性,设计了一款可应用于户外的开关电源。与传统适配器电源相比,该设计可以增强笔记本电脑的使用范围。利用开关电源仿真软件LTspice Ⅳ进行仿真并对该款户外开关电源工作原理进行了详细分析。仿真与实验结果表明,在不同工作模式及不同带载情况下,该户外电源能输出纹波较小的稳定电压。According to the using characteristics of power adapter of the current mainstream notebook computer, this paper designs a switching power supply can be used in outdoor. Compared with the traditional adapter power supply, the apphcation design can enhance the use of the laptop. Through the switching mode power supply simulation software LTspice IV to simulate and analyze its working principle in detail, the experimental tests show that in the case of different operating modes and different load, the outdoor power can output stable voltage with less ripple. ~.
