摘要
仿真分析是一种重要的辅助教学手段,为了全面掌握基本知识和提升自学能力,电气工程专业学生应该学会熱练地使用几种多域仿真软件。本文在描述磁性元件的磁滞回线概念基础上,采用MATLAB/Simulink仿真分析了几种典型的电力电子变换器,给出多种工况下变压器和功率电感的磁滞回线,包括磁滞小环。借助该教学设计,可以加深学生对电力电子变换器工作原理的理解,并对磁学产生足够的认识和兴趣。
Simulation analysis is an important auxiliary learning method.In order to master basic knowledge and improve self-learning ability,students in the field of electrical engineering should learn to use several multi-field simulation software lilfully.In the paper,the basic concept of hysteresis loop of power inductor is described firstly,then several basic power electronic converters are simulated by means of MATL AB/Simulink,and the hysteresis loops of the employed power inductors under different operating conditions are given,including hysteresis major loops and minor loops,by which students can get deeper understanding of the operating principles of power electronic converters,and students can also have enough knowledge and interest in magnetics.
