Power Electronics and Electromechanical Energy Conversion
Proposed Project Fall 2011 The Electric Bungee The
ultimate power electronics and electromechanical energy efficiency contest.
Can you store gravitational potential energy in an ultracapacitor, just as a
bungee jumper stores it in a spring?
Controlled use of energy is essential in modern society. As advances in
power electronics extend the capability for precise and efficient control of
electrical energy to more applications, economic and environmental
considerations provide compelling reasons to do so. In this class, the
principles of power processing using semiconductor switching are introduced
through study of pulse-width-modulated dc-dc converters. High-frequency
techniques such as soft-switching are analyzed. Magnetic circuit modeling
serves as the basis for transformer, inductor, and electric machine design.
Electromechanical energy conversion is studied in relation to electrostatic
and electromagnetic motor and actuator design. Applications to energy
efficiency, renewable energy sources, robotics, and
micro-electromechanical systems are discussed. Laboratory exercises lead
to a project involving switching converters and/or electric machines.

enrolled in the course.
If you experience trouble with the
Blackboard site, here's how to get help:
- For a problem with the 125 site, or if you need get access to it,
email the people who maintain the 125 site: Charlie Sullivan and Kim Cooper.
- If there seems to be trouble with the Blackboard system:
- Email Barbara
- Email Mark O'Neil.
all else fails and it's really urgent (you need access to study
materials and a test is coming up shortly, and you are sure that the
system is down because you've checked with others in the class and they
can't get on either), email
or (probably better) call the machine room at 646-2075.
