The MOSFET module realizes a full-bridge dc/dcconverter which provides adjustable dc voltage to the dc traction motor and allows current tofollow in both direction. As a result, the DC traction motor can be operated in four-quadrant andunder different speed. (a) Page 23.280.3 (b) Figure 1 (a) golf-cart and (b) platform project structureIn order to

This is a web-based “clicker” type systemin which the students provide immediate feedback to instructor questions. An MS PowerPointpresentation was created for each homework assignment in which each problem was stated andmultiple potential answers for each problem were provided. The students would provide theiranswers to each question. This enabled the instructor to immediately determine if the problemwas well understood by the majority of the class. If a number of students
