基于MANTLAB的DC-DC电路主电路仿真分析 摘 要 DC-DC电路(直流变换电路)在电力电子的领域里有很广泛的应用，它具有低功耗、高转换效率、小型、轻便等优点，随着各种便携式电子设备的发展和普及，小体积的DC-DC转换器越来越受到人们的推崇也迎来了更大的发展空间。所以，对于DC-DC电路的研究就具有很大的前景和意义。 本文首先介绍了DC-DC变换电路的分类和六种基本电路的结构，包括隔离型的电流可逆斩波电路和多相多重斩波电路，非隔离型的正激电路、反激电路、半桥电路和全桥电路。然后，介绍了每种电路的工作原理与过程。并在MATLB软件中构建了各个电路的仿真模型和参数，利用MATLAB软件对各个电路调试和仿真，最终得到了比较理想的仿真结果。 最后，本论文在电路分析和子的基础上，仿真软件对电路进行仿真，验证各主电路工作原理理论波形理论分析和设计的正确性，Abstract DC-DC circuit in the field of power electronics has a very wide range of applications, it has low power consumption, high efficiency, small size, light, etc., with a variety of portable electronic devices development and popularization of small volume of the DC-DC converter is respected more and more people also ushered in a larger space for development. So, for DC - DC circuit research on great prospects and significance This paper first introduces the classification of DC - DC conversion circuit and six basic circuit structure, including the isolation of current reversible chopper circuit and multiphase multiple chopper circuit, the isolation of excitation circuit and fly back circuit, half bridge circuit and the whole bridge circuit. Then, the paper introduces the working principle and process of various kinds of circuit. And in the MATLB software to build the simulation model and the parameters of each circuit by using MATLAB software for each circuit debugging and simulation, finally got ideal simulation result. Finally, we work on the principle of each circuit analysis and sub-model construction, based on the use of MATLAB simulation software for each circuit simulation, through the observation and analysis of simulation results verify the working principle of the main circuit and the theoretical waveforms. To prove the correctness of theory analysis and design, to make the reader know the DC-DC circuit can have a deeper level of.
