摘要:電能分為直流和交流兩種類型，電力變換的基本類型就是這兩種電能之間的四種變換形式，包括整流、逆變、斬波、交流電力變換。在電力電子電路如變流裝置的設(shè)計過程中，需要對設(shè)計出來的初步方案(電路)及有關(guān)元件參數(shù)選擇是否合理，效果如何進行驗證。如果通過實驗來驗證，就要將設(shè)計的系統(tǒng)用元件安裝出來再進行調(diào)試和試驗，不能滿足要求時，要更換元件甚至要重新設(shè)計、安裝、調(diào)試，往往要反復多次才能得到滿意的結(jié)果。這樣將耗費大量的人力和物力，且使設(shè)計效率低下、耗資大、周期長。如果使用MATLAB/Simulink軟件來對電路進行仿真試驗，則可大大地節(jié)約開支，提高設(shè)計效率，縮短設(shè)計周期。 本文主要以MATLAB/Simulink仿真軟件為基礎(chǔ)，首先，介紹本課題的研究內(nèi)容及研究的意義；其次，介紹MATLAB/Simulink的基本用法，如何進行建模與仿真；然后，利用該軟件針對電力電子變換的四種變換電路建立仿真模型、參數(shù)設(shè)置與仿真分析。仿真結(jié)果表明該方法與理論分析結(jié)果一致，從而驗證了仿真建模的準確性和有效性。 關(guān)鍵詞：MATLAB/Simulink；整流；逆變；斬波；電力變換；建模與仿真
Abstract:DC and AC power is divided into two types, power transform the basic type is the two kinds of power between the four kinds of transformation form, includes a rectifier, inverter, chopper, AC power conversion. In power electronic circuits such as converter design process, need to design out of the initial scheme ( circuit ) and the relevant component parameters is reasonable, the effect how to validate. If the experiments to verify the design of the system, will use element mounted out the debugging and testing, can not meet the requirements, to replace the components or even to design, installation, commissioning, often repeated several times to obtain satisfactory results. It will cost a lot of manpower and material resources, and the design efficiency is low, cost is big, long cycle. If you use the MATLAB/Simulink software to circuit simulation test, it can greatly reduce costs, improve the design efficiency, shorten the design cycle. This paper takes the MATLAB/Simulink simulation software as the foundation, first, introduced the research content and research significance; secondly, introduces the basic usage of MATLAB/Simulink, how to carry on the modeling and simulation; then, the use of the software for power electronics transform of four circuit simulation model, parameter setting and simulation analysis. The simulation results show that this method is consistent with the theoretic analysis, which verifies the accuracy and the validity of simulation modeling.
