摘要
本文阐述了升压式DC-DC变换器的基本原理,分析了其基本结构,并根据其基本理论提出了一种简单的升压式宽动态负载范围连续电流模式的DC-DC拓扑结构的设计方法,其中主要包括升压式DC-DC的主变换电路和PWM控制器的设计。在此基础上,运用Hspice仿真工具建立了电路模型,并完成了系统仿真验证。
In this article,the principles of the boost.DC-DC converter are described,the basic structure of which is then be analyzed,.And a simple design method for the boost DC-DC converter in ccm mode over a wide range of load conditions is also presented. It include the design of the main boost converter and pwm controller.Basis on that,the system model is also established by Hspice Tool. At the same time, the simulation of the system model are accomplished through
