ABSTRACT

The course of Energy Conversion is a required course in EE curriculum at Texas A&M University – Kingsville (TAMUK). Traditionally, this course dealt with topics of transformers and electric machines, and was normally presented under the assumption of steady-state conditions. Students usually thought that the course was old-fashioned and boring, which greatly limited student’s ability to understand wide control applications of electric machines. However, modern electric machines are widely interacted with power electronics, DSP and digital control technology. These technology changes are not reflected in traditional teaching structures of the course. This paper gives the restructuring of the course at TAMUK through an integrative teaching approach and computer assisted teaching methodologies so as to provide students a complete view of an electric drive system that consists of electric machines, power electronics, controllers, power supply systems, and mechanical loads.

1. INTRODUCTION

As the technology of Electrical and Computer Engineering (ECE) grows, undergraduate programs are under constant pressure to keep content up-to-date within a four-year context of a fixed number of credit hours allowed for graduation. This technology change also challenges traditional teaching structure to one of the core courses, Energy Conversion or Electric Machinery, in general ECE programs.

At Texas A&M University – Kingsville, the course of Energy Conversion also known as Electric Machinery, used to cover three-phase circuits, transformers, DC generators and motors, AC synchronous generators, and AC induction motors [1, 2]. The course basically dealt with line-fed and steady-state DC and AC electric machines with no attempt of controlling machine speed, torque, and/or position. This had greatly limited student’s capability to understand wide
