Development of a Modern DSP-based Laboratory for Power Electronics Education

工程-工程技术 (58) 该项目正在通过改造明尼苏达大学开发的实验室来开发电力电子高级课程的实验室活动。对明尼苏达大学模型的修改包括通过在预实验室中包含 PSpice 仿真来特别强调电力电子的设计方面。最先进的基于数字信号处理（DSP）的软件正在被重新配置以控制电力电子转换器。正在开发的新实验室包括： 1）DSP控制器和逆变器简介； 2) AC-DC 转换器，包括使用 PSpice 仿真分析二极管整流器电路中的输入电流谐波和输出电压纹波，以及使用 DSP 控制的单相电压源 PWM 逆变器的基本操作； 3) 使用 DSP 控制器的电机控制应用。 目标是重振人们对电力和电力电子领域的兴趣，并帮助解决快速发展的电力电子多学科领域的学生入学率低的危机。领导团队正在评估实验室对代表性不足的学生群体的学习的影响。该项目得到了德州仪器公司的支持。通过网站、研讨会和会议进行传播。

Engineering-Engineering Technology (58) The project is developing laboratory activities for a senior course in power electronics by adapting labs developed at the University of Minnesota. Modifications to the University of Minnesota Model include placing special emphasis on design aspects of power electronics by including PSpice simulation in pre-labs. State-of-the-art Digital Signaling Processing-based (DSP) software is being reconfigured to control power electronic converters. New laboratories that are being developed include: 1) Introduction to DSP Controller and Inverter; 2) AC to DC converter that includes analysis of input current harmonic and output voltage ripple in diode rectifier circuits with PSpice simulation, and basic operation of a single phase voltage sources PWM inverter using DSP control; and 3) Motor control application using the DSP controller. A goal is to revitalize interest in the area of Electric Power and Power Electronics and help address the low student enrollment crisis in the rapidly developing multidisciplinary field of Power Electronics. The leadership team is assessing the impact that the laboratories have on learning for underrepresented populations of students. The project is being supported by Texas Instruments Inc. Dissemination is through a website, workshops and conferences.
