基于Simulink的变流技术仿真实验研究

Simulation Experiment Research of Power Electronic Converter Technology Based on Simulink

针对变流技术中典型的几种电路如整流、斩波、ZVS-PWM变换电路、三电平SPWM逆变电路以及斩控单相调压电路利用Simulink建立了系统模型,对电路仿真输出进行了分析与研究,将部分电路在仿真的基础上进行了FFT分析,进一步增加了电力电子变流技术实验内容、深度与广度,扩宽了实验者的思路。与传统电力电子变流技术实验相比,通过对这几个难度递增的基本电路进行实验仿真分析,使实验者从验证性实验转变为设计性、研究性及综合性实验,极大的调动了实验人员的主观能动性,为变流技术实验研究提供了有益的帮助。

Some typical models are established by Simulink such as rectifier circuit,chopper circuit,ZVS-PWM converter circuit,three-level SPWM inverter circuit and chopped single-phase voltage regulator circuit. The circuit simulation outputs are analyzed and researched,FFT analyses of some of the circuits are completed based on simulation results. These extensions increase content,depth and breadth of experiments of power electronic convert technology,widen the consideration area of the experimenters. Compared with the traditional power electronics experiments,these experiments have stepping difficulty levels. The experimenters can transform themselves from verifying experiment to designing a comprehensive experiment,hence the reform can enhance the subjective initiative of the experimenter and provide useful help for power electronics experiments.
