Enhanced problem-based learning of power converter theories and implementations with behavior model simulations

Recently, the increasing demands for high efficient power conversion systems and the rapid advancement in semiconductor devices have made the power converter design technique a necessity for electronic engineers. To speed up the learning process, the problem- based learning approach and behavior model simulations are used to redesign the first power converter design course in Lunghwa University of Science and Technology. Problems and course materials are carefully devised to help students acquire the knowledge to systematically design a power converter, to implement the converter by using PWM control ICs, and to validate its performance via behavior model simulations. The course by using problem based learning approach will also prepare students the skills in 1) logical analysis, 2) drawing a conclusion from group discussions, and 3) cooperation with others. The feedbacks of the students from the midterm and final examinations, the questionnaires, and the answers to the teacher´s quizzes during classes show the effectiveness of this approach.
