摘要
在运用Multisim软件分析高频谐振功率放大电路的教学中,学生常常因不熟悉仿真软件的操作而无法解决复杂的电路问题.从Multisim软件的应用出发,通过对高频谐振功率放大电路的分析,阐述基于Multisim软件的电路设计、虚拟仪器使用、测量结果读取、多种仿真分析功能的应用,对电流探针、AC扫描、参数扫描等功能的运用进行说明.教学实践表明:使用Multisim软件的虚拟仪器库和仿真分析功能实现高频谐振功率放大电路的仿真测试和研究,让复杂抽象的电路原理直观化,可以克服硬件实验条件不足的困难,有利于培养学生创新思维和解决实际电路问题的能力.
When teaching the high-frequency resonant power amplifier by Multisim software,we found that students can't solve complicated circuit problems because they can't grasp the software proficiently.Aiming at improving students'ability to solve complex circuit problems,this paper starts from analysis of the high frequency resonant power amplifier circuit through application of Multisim software.The circuit design,usage of virtual instrument,acquisition of measurement result,the application of various simulation analysis functions,especially the usage of current probe,AC sweep and parameter sweep are expounded in detail in this paper.Teaching practice has proved that Multisim software can not only overcome the defects of insufficient hardware experimental conditions,its huge virtual instrument library and simulation analysis function can also make the complex and abstract theory intuitive.So Multisim software has a good role in promoting studentsability in innovation thought and solving practical circuit problems.
