IEEE Dayton Section

Abstract: Power flow control techniques have been practiced, from using inductors, capacitors, transformers and load tap changers in the earlier days of electrical engineering to power electronics-based solutions in recent years. Even though the costs and complexities of the available solutions vary widely, the basic underlying theory of power flow control is still the same as it always has been. The question is which solution one should employ. The answer depends on knowing what the true need is. The power industry’s pressing need for the most economical ways to transfer bulk power along a desired path may be met by building new transmission lines, which is a long and costly process. Alternately, it may be quicker and cheaper to utilize the existing transmission lines more efficiently. The key is to identify the underutilized transmission lines and harness their dormant capacity to increase the power flows to the lines’ thermal limits. The presentation is designed to provide the basic principles of power flow control theory, an overview of the most commonly used power flow controllers, and future trends. The audience will hear from an expert who actually designed and commissioned a number of power electronics-based FACTS controllers since their inceptions in the 1990s.

This Friday 3 pm is open to students (primarily Air Force Institute of Technology, but all invited) presenting a 15 min (or so) talk on what interests them. Open to any & all students, so pass the word. This is a good place for young folks to teach something new to old folks who still like to learn, & / or forgot what it was like to be young. Co-sponsored by: Wright-Patt Multi-Intelligence Development Consortium (WPMDC), The DOD & DOE Communities Speaker(s): Timothy Wolfe, Agenda: TOPIC: Discussion of Active and Potentially Sponsored Research Projects in Remote Sensing and Electronics DETAILS: Review of topic lists provided by NASIC and the US Coast Guard with the possibility of sponsorship, covering a variety of electrical, computational, and material engineering topic. Also, an overview of a currently sponsored project in collaboration with the AFIT Applied Physics NEAT Center (Nuclear Expertise for Advancing Technology) taking place at Sandia National Laboratory Tandem Ion Beam facility and the National Ignition Facility at Lawrence Livermore National Laboratory will be discussed, with an eye toward the need for future and on-going support from electrical engineers.

This talk uses revealed preferences ideas stemming from microeconomics to develop inverse reinforcement learning methods in the context of cognitive radars. The talk comprises three parts. The first part develops inverse reinforcement learning algorithms to identify if a radar is cognitive, and to estimate the radar's utility function and constraints. The second part of the talk discusses how to design a radar that hides is cognition, i.e. how a cognitive radar can act dumb. Finally, we briefly discuss real time inverse reinforcement learning based on stochastic Lagenvin dynamics algorithms.

Co-sponsored by: Wright-Patt Multi-Intelligence Development Consortium (WPMDC), The DOD & DOE Communities Speaker(s): Eric Fairchild, Agenda: TITLE: GaN COTS HEMT Reliability Test Plan ABSTRACT: Commercial off the shelf (COTS) Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs) are widely used in high power/frequency applications due to GaN’s electrical properties which include a wide direct bandgap of approximately 3.4eV. GaN’s inherent wide spacing between the valence band maximum and conduction band minimum are what allow GaN to perform at higher power levels, frequencies, and temperature conditions than that of conventional semiconductor materials, such as silicon. However, unlike silicon-based devices which have established qualification standards, qualifying GaN devices into new and existing systems takes additional time because there is currently no widely accepted standard for evaluating the reliability of GaN transistors. This test plan seeks to detail the I-V characterization and reliability testing on a number of GaN COTS devices from various manufacturers to identify gate leakage current as an identifying factor of device reliability.
