讲解了DC-DC变换器的基本工作原理,以及其中一个十分重要的使用参数——转换效率.基于转换效率的问题,仿真设计该电源需要用到电源芯片LM3150 以及利用到美国设计的用来仿真的软件,WEBENCH Power Designer设置开关电源的每个元器件数值,并综合考虑其价格、频率、精巧设计等方面的升级优化.最后通过软件仿真检验到设计出来的电源的稳定性很强,且转化效率更高.
Design and Simulation of Buck DC-DC Power Supply Based on LM3150
In the convenient portable power supply,Buck DC-DC power supply is very common in life.In this paper,it explains the basic working principle of DC-DC converter,and one of the very important parameters-conversion efficiency.Based on the conversion efficiency,the simulation design of the power supply requires the use of power chip LM3150 and simulation software designed in the United States.WEBENCH Power Designer sets the value of each component of the switching power supply,and comprehensively considers its price,frequency ex-quisite design and other aspects of the upgrade and optimization.Finally,through the software simulation test,the stability of the designed power supply is strong,and the conversion efficiency is higher.
