A software system to study and design ideal UPS systems forpower electronics course is featured in [3]. The ideal UPS system is fostered by the creation ofan integrated graphical interface calculating the optimal configuration of each component.Though the system has a notable visual interface, it focuses only on the construction aspect, notthe monitoring of a system that has already been assembled.Integration of custom-designed hardware into laboratory and the classroom is growing at anumber of universities.

The course focuses on getting a hardware/software codesign experiencethrough a combination of lectures and laboratory sessions. The laboratory component will be thefocus of the paper. The course has the following learning outcomes:Laboratory learning outcomes:L1. Students will develop a capability of embedded systems design by programming a microcontroller board using C with modern development tools.L2. Students will develop a custom reconfigurable embedded platform using FPGA based development boards including appropriate drivers for peripherals.Course Outcomes:After successfully completing this course the student should be able to:C1.

Simulink and dSPACE control platform. Two 200W DC machines rated at 40VDC and4000 rpm were used. The DC machines were controlled using a pulse width modulated (PWM)power converter. This project was part of an undergraduate research supported by NSF and theUniversity of Minnesota Research Experiences for Undergraduates (REU) program.I. IntroductionThe objective is to develop a system that emulates a wind turbine. Previous efforts in thisdirection have employed separately excited DC machines1,2 with power ratings in the multiplehorsepower range. The intended application of the system described in this paper is forundergraduate laboratory courses. Thus, a system that works at lower voltages is desired.Existing laboratory equipment such as DC
the lecture and lab activities described herein assisted their learning.IntroductionIn 1975, an MIT study published by ASEE1 noted that "educational experience in design shouldbe promoted as early as possible...and should be available as an integrated part of the engineeringcurriculum." A subsequent push to "integrate design throughout the curriculum"2 led programsto add design content in lower-division (e.g., freshman engineering) courses3,4 and augmentdesign activities in upper-division courses.Instructional laboratories are a natural setting for design5, but meaningful exercises in lower-division courses pose a challenge. Several efforts have been reported which involve the addition ofelectronics topics to an introductory circuit analysis
