摘要
电力电子电路设计时参数的选择、计算,往往比较复杂,利用Matlab中的电力系统工具箱,不用进行编程,也无需推导电路、系统的数学模型,就可以很快得到系统的仿真结果。以Buck电路为实例,讨论了其输出电压脉动产生的原因,并利用Matlab建立了电路模型,通过对仿真结果分析将有关参数进行了修改,从而确定了最佳参数模型。可以看出Matlab作为一种新型的高性能的语言,为电力电子技术的研究与应用实现提供了理想的工具。
This is a complex problem in selecting and calculating the parameter, when designing the power electronic circuit. By using the power systems toolbox in Matlab , users can quickly find out and analyze the results from simulation, don＇t need know the mathematics model and programming. This paper discusses the reason of voltage ripple in buck chopper output, sets up the system model in Matlab,and modifies the parameter by analysing the simulation result,in the end,it confirms the optimum parameter model. Matlab is the ideal tool used for the research and application of power electronics as a new style and high - powered language.
