- Associate Professor
- Member of the Faculty at the University of Kentucky His
Since 1993 Dr. Radun has been a member of the faculty at the University of Kentucky His research interests includes power electronics, electromagnetics, and power semiconductors. A major component of Dr. Radun's research is the development of switched reluctance motor (SRM) based aircraft generator systems. This includes developing SRM models, iron loss models and complete closed loop system models. Both DC and AC systems have been addressed. His work has focused on developing detailed computer model based system design and analysis tools for SRMs and the systems that employ them. These computer models have been validated by applying them to the experimental 250kW SRM based starter/generator developed jointly by the General Electric and Sundstrand Corporations and funded by the US Air Force's Wright Laboratory. Dr. Radun has also conducted research to develop a 125 KW MOS controlled thyristor (MCT) based inverter/converter. This has included investigating the causes of observed MCT failures through detailed finite difference modeling of the MCTs. At the present time Dr. Radun is developing a model and the controls for a switched reluctance AC /cycloconverter system. He is also studying the stability of a future DC aircraft power system consisting of a SRM based starter/generator and high efficiency power electronic loads. At the present time Dr. Radun is also developing a low frequency (2Hz) high voltage (+/- 5,000V) power source.
Job Titles:
- Professor, Center Director
Dr. Heydt has done research work primarily in the area of electric power quality and distribution engineering. He is a co-author of the HARMFLO harmonic power flow study software. He has worked in the following related areas recently: applications of wavelets in power quality assessment; applications of chaos theory in power engineering; applications of advanced signal processing in power quality data analysis; development of voltage conditioning hardware (e.g., the TVR, the DVR) and their analysis; bus voltage sags; instrumentation of power quality; use of the global positioning satellite in transmission circuit instrumentation (e.g., measurement of overhead transmission line sag). Dr. Heydt is also the center director for the center for the Advanced Control of Energy and Power Systems, an NSF supported center devoted to power engineering.
