Funding is leveraged with minimal risk

Industry sponsors provide cash funds on a funding unit

basis of at least $10,000 per year as unrestricted

research funding

Fee is kept low so that engineers and first level

engineering supervisors can be our champions

Sponsorship funding is less than 1/4 of total funding

Separate contracts with sponsors are the largest part

Sponsorship fee supports basic research likely to

impact a significant number of sponsors

One company can have up to five sponsorship units

355 Electromechanical Energy Conversion. Energy storage and

conversion, force and emf production, coupled circuit analysis of

systems with both electrical and mechanical inputs. Applications to

electric motors and generators and other electromechanical

transducers.

356 Electric Power Processing for Alternative Energy Systems.

Introduction to electrical power processing technologies that are

necessary to convert energy from alternative sources into useful

electrical forms. Several specific alternative energy sources are

examines, providing platforms for introducing basic concepts in

power electronics, electric machines, and adjustable-speed

drives.
