 摘  要
目前，在中国许多高校中使用的教学仪器，仍大多为相当落后的传统仪器。随着科学技术的不断发展以及相应学科高等教育课程教学内容的更新，传统仪器日益暴露出一些缺陷和不足。为了改善实验条件，改善实验教学方法，更新实验教学内容，提高实验教学课程的开设水平，把虚拟仪器引入实验教学已成为一种必然趋势。本文就是基于虚拟仪器在电力电子实验教学的应用设计。
虚拟仪器（Virtual Instrument）是现代计算机计算和仪器技术相结合的产物。将虚拟仪器技术引进实验教学，目的是更新实验设备，降低实验设备购置费用，减小实验测量过程中的人为误差，提高实验测量的准确度；在激发学生自主学习的积极性、促进学生动手实践和增强创新意识的方面意义重大。
 远程虚拟实验室系统借助虚拟仪器技术和LabVIEW强大的数据分析处理功能，能提高实验效率，降低实验成本，减少设备维护。远程虚拟实验室具有使用方便、界面友好、与计算机同步发展等特点，这将导致降低实验成本，更新教学方法，提高教学质量。

 Abstract
 At present, the teaching instrument that used in a lot of universities in China is still mostly quite backward traditional instruments. With the developing of science and technology and renewal of corresponding content of courses of higher education course, the traditional instrument exposes some defects and deficiencies day by day. In order to improve the experiment conditions, improve the teaching method of the experiment, upgrade the content of courses of the experiment, improve the competence of offering of teaching course of the experiment, leading the virtual instrument into experiment teaching has become a kind of inexorable trend. This thesis is about the designs of application in experiment teaching of motor with the virtual instrument.
 The virtual instrument is a product that the modern computer calculated and instrument technology combined together. Importing the virtual instrument technology into experiment teaching, the purpose is to upgrade experimental installation, reduce the purchase expenses of experimental installation, reduce the human caused error in the measuring of experiment, improve the accuracy that the experiment measures; There is great significance in the respect of exciting the enthusiasm that students study independently, promoting students to start to practise and strengthening innovative consciousness.
 Remote virtual laboratory system using LabVIEW virtual instrument technology and powerful data analysis features, can improve the experimental efficiency and reduce experimental costs and reduce equipment maintenance. Remote virtual laboratory with easy-to-use, friendly interface, with features such as the simultaneous development of the computer, which will lead to a reduction in the cost of the experiment, update teaching methods, improving the quality of teaching.
