摘要
本文介绍了DC-DC变换电路原理及分类;讨论了三种典型DC-DC变换电路即Buck电路、Boost电路和Buck-Boost电路的原理、结构、电压变换关系,并在Matlab软件建立仿真模型验证了理论分析的正确性;比较了这三种典型DC-DC变换电路的优缺点。
In this paper,the principle and classification of DC-DC transform circuit was introduced.Besides,the principle,the composition and the change of the voltage of the three kinds of typical DC-DC transform circuit which are called buck circuit,boost circuit and buck-Boost circuit were discussed.In addition,the analysis was verified by using Matlab,and the advantages and the shortcomings of the three DC-DC transform circuits were compared.
