Title: ENERGY CONVERSION
Credits: 3
 

Catalog Description:
Energy technology and resources: Fossil fuels, nuclear, solar, and other types of energy. Three phase systems and magnetic circuits. Transformers: Ideal and physical models and equivalent circuit, and transformer testing. Electromechanical energy conversion. Efficiency and process performance. Sensors and actuators: Relays, stepper and positioning systems, switched reluctance machines, synchronous reluctance machines, direct current (DC) machines. Symmetrical alternating current (AC) synchronous machines. Symmetrical AC induction machines.

Prerequisite: EE 201.

Coordinator: Okyay Kaynak, Professor of Electrical Engineering

 
Goals: This course aims to expose the students to the principles of electromechanical energy conversion, starting with magnetic circuits and transformers. The mechanism of force and torque production is explained, followed by the operation of dc and ac machines. Equivalent circuits are given as a basis for analysis.

 

Learning Objectives:

At the end of this course, students will be able to:

   1. Explain the operation of transformers and basic dc and ac machines
   2. Derive equivalent circuits for transformers and electrical machines.
   3. Solve problems on the operating conditions of transformers and electrical machines.
   4. Predict the operating characteristics of electrical machines
   5. Describe how the speed of dc and ac motors are controlled.

Prerequisites by Topic:


   1. Linear algebra
   2. Basic knowledge in electricity and magnetism
   3. Linear circuit analysis
   4. Phasor diagrams

 

Topics:

   1. Review of Basic Laws of Electromagnetism (1 week)
   2. Magnetic Circuits (2 weeks)
   3. Principles of Electromechanical Energy Conversion (2 weeks)
   4. Transformers (2 weeks)
   5. Production of of force and torque (1 week)
   6. DC Machines and Control of DC Machines (3 weeks)
   7. AC Machines and Control of AC Machines (2 weeks)
   8. Permanent Magnet Motors, Stepper motors, Switched Reluctance Motors, Brushless DC Motors, Appliance motors (time permitting)


Course Structure:
The class meets for two lectures a week, one consisting of two 50-minute session, the other one 50-minute session. 2-4 sets of homework problems are assigned per semester.  There are two in-class mid-term exams (open book) and a final exam (hybrid).

Computer Resources: None

 Laboratory Resources:
None.
 

Grading:

   1. Homework sets (15%)
   2. Two mid-term exams (25% each).
   3. A final exam (35%).


Outcome Coverage:

       *Apply math, science and engineering knowledge.  Different tools from mathematics (linear algebra, complex variables, phasor representation) as well as from sciences (physics) and engineering (dynamics) are utilized during lectures, homework sets and exams. Input/output representation and equivalent circuit concepts are introduced.
   

     *Design a system or a component to meet desired needs.  The problems solved in the class and set for the homeworks and exams require the design of magnetic circuits to meet some performance criteria (such as maximum efficiency). Students become able to relate the performance characteristics of electrical machines to their design parameters.
   

      *Recognize the need for, and an ability to engage in life-long learning. Throughout the course, how fast the technology is changing, related even to such a classical course is stressed. In the face abundance of knowledge, the paradigm shift from “just-in-case teaching” to “just-in-time learning” is explained.
