that in order to enhance students’ learningon power electronics subjects, the best way is to let them apply the knowledge they learn in lecturesin actual design and see to it that their designs actual work. Our teaching philosophy is to teachstudents to design power electronics circuit based on circuit theories first. Then they simulate andimprove their designs using commercial simulation software like PSPICE or SABER. After that,they build prototype(s) in the laboratory, and finally they test their design and prove that all designcriteria are met. The design of our power electronics laboratory follows the proposed philosophyclosely.Characteristics Curve of Switching Devices Since all power electronics circuits or systems consist of

[4] As he interviewed a group of students at the end of each academic year, probing theirviews of their university experiences, he observed patterns of thinking that were hierarchical andchronological. These patterns described an intellectual development path that all studentsseemed to follow and that Perry translated into a nine-stage model of development that hevalidated by a second, more extensive, longitudinal study.The model, a portion of which is summarized in Table 1, describes the stages students passthrough as they mature in their understanding of the nature of knowledge, use of evidence, andopen-ended problem solving.

For instance, Dym (1994) encourages “interactive dialog” between the instructor(s)and students so that students learn that a seemingly simple statement such as “a safe ladder”involves not only clarifying objectives, but interacting with individuals who hold variousviewpoints, and developing design specifications that can be calculated. Similarly, Dally andZhang (1993) emphasize that the teaching and learning process involves two-waycommunication between the student and faculty member. They describe the role of the facultymember as consultant and coach, providing assistance and encouragement. At times

A typical com-puter assignment in that era would require the student to carry out the followingtasks: 1.) Derive the model equations for the problem at hand, 2.) Find an appropri-ate numerical method to solve the model (mostly NLE’s or ODE’s), 3.) Write anddebug a FORTRAN program to solve the problem using the selected numerical algo-rithm, and 4.)

= 50 rad/s, or f3dB = 7.96 Hz. Since it is unlikely thatmeaningful temperature variations will fluctuate more rapidly than 7.96 Hz, the low-pass filterprovides a convenient means of filtering out high-frequency noise. Closing the G-pad provides a reference from ground to the filtered low signal via a 100KΩresistor. The 100KΩ resistor ensures that only enough current passes to provide a reference toground so that the filtered high and low signals can still float within the common mode range.With this arrangement, the differential input will reject up to 10 Volts of EMI energy on thesignal wires8.
