Improved efficiency in medium-power flyback converters

Creator:: Ruttanapaibooncharoen, Surin
Abstract:: Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less...

Wind Farming vs Mobile Gear Fishing: is there room for a bargain?

Creator:: Wiersma, Joshua
Abstract:: A private power company, Cape Wind Inc., wants to develop the largest wind farm in United States history off the coast of Cape Cod Massachusetts in a twenty-five square mile area of Nantucket Sound known as Horseshoe Shoal (HSS). However, Cape Wind must compete for the use of this area...

Micro adiabatic combustion engine : concept development, simulation and combustion experiments

Creator:: Chewning, Scott R.
Abstract:: The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

Simulation of a high voltage direct current transmission system in an electromagnetic transients program using semiconductor terminals

Creator:: NwaChukwu, David O.
Abstract:: In high voltage direct current(HVDC) systems transmission technology, a.c. power is converted(rectified) to d.c. power by means of a controlled rectifier bridge. This d.c. power is then transmitted through a d.c. link to another converter(inverter) where it is converted back to a.c. power by means of another controlled rectifier bridge....

On the study of WEC prototype advancement with consideration of real-time life extending control

Creator:: Stillinger, Chad J.
Abstract:: Renewable energy is a topic of significant interest and importance in the world today. Ocean wave energy, particularly in areas such as the Oregon Coast, has considerable potential as a renewable resource. However, to rightly evaluate the overall cost of energy for wave energy converters, survivability and maintenance issues must...

A linear test bed for characterizing the performance of ocean wave energy converters

Creator:: Hogan, Peter M.
Abstract:: Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

A Microgrid Design Case Study : Synchrophasor Placement and Development of a Protection Laboratory for the Oregon State University - Corvallis Campus

Creator:: Huo, Chen
Abstract:: In the past two years, Oregon State University (OSU) Corvallis campus suffered several power outages. The estimated cost of one of those outages was close to a million dollars worth of equipment and impact on research projects. Meanwhile, the campus grid operates with severely aging power assets. The reliability of...

Towards reliable and survivable ocean wave energy converters

Creator:: Brown, Adam C.
Abstract:: Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...
