摘　　要：分析电力电子技术课程传统教学模式的缺陷。在NI Multisim11仿真软件的虚拟实验工作平台中,完成三相半波可控整流电路和正弦脉宽调制(SPWM)逆变电路的设计。运用NI Multisim11仿真软件提供的虚拟仪器仪表以及傅里叶分析方法,对所设计的电路进行仿真测试和分析。这种计算机仿真设计与仿真实验同步进行的方法与传统的设计方法相比,体现了电子设计自动化方便、高效和低耗的优越性。因此,NI Multisim11仿真软件不仅是电力电子技术课程很好的教学辅助工具,也是电气工程设计人员理想的设计工具。This paper analyzes the drawback of traditional teaching model of power electronic course.Using NI Multisim11 simulation software as virtual experimental platform,complete the design of the three-phase half-wave controlled rectifier circuit and sinusoidal pulse width modulation（SPWM） inverter.Taking advantage of virtual instruments and Fourier analysis method provided by NI Multisim11,we do the simulation testing and analysis against the designed circuit.Compared to traditional design method,this kind of method which combines computer simulation design and simulation experiment shows the convenience and high efficiency of Electronic Design Automation（EDA）.In a word,NI Multisim11 simulation software is not only a great teaching aid in power electronic course,but also an ideal design tool for electrical engineer.
