摘要通常我们所说的磁集成技术，就是将变换器中的两个或多个分立磁件(Discrete Magnetics, DM)绕制在一副磁芯上，从结构上集中在一起[3]。它通过一定的耦合方式，合理设计参数,使电力电子装置中的磁性元件(变压器、电感等)集成在一个磁芯上,将多个分立元件变成一个集成磁元件[2]。 本文首先引入了磁集成技术的概念，接着介绍了国内外磁集成技术的发展历程，从中体现其相应的技术优势。 论文的第二部分将介绍磁集成技术中的磁件分析方法，包括建立磁件电路模型的方法，磁集成技术的具体应用中的电感与电感集成，电感和变压器集成等。 第三部分将结合电路图分析倍流整流半桥变换器的工作原理，为引入磁集成技术打下基础。 论文的最后将分析基于磁集成技术的倍流整流半桥变换器的工作原理，并设计参数，运用MULTISIM 软件对其进行仿真，以此来进一步加深我们对磁集成技术的了解。 27138

Title Analysis and design of integrated magnetic power electronic converter
Abstract
We usually say the magnetic integration technique, that is, the converter of two
or multiple discrete magnetics (discrete magnetics, DM) wound on a pair of magnetic
core, from the structure concentrated together [3]. It through a certain way of
coupling, reasonable design parameters and the power electronic devices in the
magnetic element (transformers, inductors, etc.) integrated in a single core,
multiple discrete components into an integrated magnetic components [2].
This paper first introduced the concept of integrated magnetic technology, and
then introduces the integrated magnetic technology development process, from
reflected the corresponding technical advantage.
The second part of the thesis will introduce the magnetic pieces of magnetic
integration technique in the analysis method, including the magnetic circuit model
was set up and the concrete application of magnetic integration technique of
inductor and inductor integration, and the inductance of the transformer
integration.
The third part will be combined with the circuit diagram analysis current doubler
rectifier half bridge converter working principle, for the introduction of
integrated magnetic technology lay the foundation.
The paper finally, analysis based on magnetic integration technology times flow
rectifier half bridge converter working principle and design parameters, using
MULTISIM software to carry on the simulation, in order to further deepen our
understanding of the magnetic integration technology.
Keywords Integrated magnetic magnetic integrated magnetic circuit model Half bridge converter with current doubler rectifier
