Short Courses

Short Course 1: Lithium-ion Batteries for Pulsed Power Systems:

Abstract: The advent of high-power, high-density batteries enables the development of repetitive pulsed power systems that can either operate independent of the electrical grid or perform as an on-demand energy source for rapid charging of capacitors.  This course will discuss the integration of batteries into a pulsed power system and design challenges that need to be considered.  An overview of the available battery types and theory of operation will lead into a case study of a battery system designed and operated at the US Naval Research Laboratory, followed by a discussion of potential failure modes and proposed methods of state-of-health management.  Additional topics to be covered include cooling methods, battery management systems, and other safety considerations.

Instructor: Dr. Brett M. Huhman received the B.Sc. and M.Sc. degrees in electrical engineering from the University of Missouri and the Ph.D. degree in electrical engineering in 2003, 2006, and 2017, respectively, as well as the Professional Engineer License in electrical and electronics engineering in 2011.  From 2005 to 2007, he was a contractor at the U.S. Naval Research Laboratory (NRL) where he was involved in the development of compact pulsed power radiography devices and electromagnetic launchers.  In 2007, he joined the Pulsed Power Physics Branch of the Plasma Physics Division at NRL, continuing to work on electromagnetic launchers. Current research interests include the application of high-power lithium batteries to pulsed power systems, with an emphasis on development of state-of-health diagnostics.

 

Short Course 2: Overview of Power Semiconductor Devices:

Abstract: This short course focuses on the basics of power semiconductor devices and its performance under normal and extreme condition. The course will also include the advent of silicon carbide (SiC) in the area of high temperature and high power semiconductor devices and its comparison to silicon (Si) counterpart in terms of device performance under extreme operating condition especially in pulsed power applications. The course will begin with a brief overview of material parameters, physics of power semiconductor devices and blocking voltage capability. Power devices including P-I-N and JBS diodes, Power Metal Oxide Semiconductor Field Effect Transistor (MOSFET), Gate Turn off (GTO) device, comparison of silicon to silicon carbide power devices and power device modeling and simulation will also be discussed during the course.

Instructor: Dr. Stephen B. Bayne received his PhD, MS and BS degrees in Electrical Engineering from Texas Tech University.  After completing his Doctoral studies, he joined the Naval Research Lab (NRL) where he was an electronics engineer designing advanced power electronics systems for space power applications.  After two and a half years at NRL, Dr. Bayne transferred to the Army Research Lab (ARL) where he was instrumental in developing a high temperature power electronic and pulsed power program.  After 8 years at the ARL, Dr. Bayne transitioned over to academia where he is a Full Professor at Texas Tech University.  His research interests at Texas Tech are Power Electronics, Power Semiconductor Devices, Pulse Power and Renewable Energy.  Dr. Bayne is currently conducting research with a focus on SiC and GaN power semiconductors for pulse and continuous operation.

 

Short Course 3: DC Arc Fault Detection and Protection:

Abstract: DC based electrical power systems are required in many emerging applications, such as more electric aircraft, hybrid electric vehicle, photovoltaic power plant, residential microgrid, etc. With the development and implementation of dc based power systems, dc arc fault protection becomes an inevitable challenge for the safe operation in various applications.  This short course will cover various aspects of dc arc fault detection in emerging dc power applications. A comprehensive review of dc arc fault modeling approaches and their applications will be presented in detail.  The principles and developments of various dc arc fault detection techniques will be then introduced.  The state-of-the-art detection techniques in both literatures and commercial products will be presented.  Moreover, the detection of dc arc faults in the context of a modern dc power systems with advanced power electronics interfaces and controllers will be discussed.

Instructor: Dr. Luis Herrera is an Assistant Professor in the Electrical and Microelectronic Engineering Department at the Rochester Institute of Technology (RIT). Prior to joining RIT, he worked for the University of Dayton Research Institute (UDRI) as a Research Engineer on a project for the Air Force Research Laboratory (AFRL) in Wright Patterson Air Force Base, OH. He received his PhD in Electrical Engineering with a focus on Power Electronics and Control from The Ohio State University in 2015 and a BS in Engineering from the University of Tennessee at Martin with a minor in physics. His research interests include the integration of renewable sources and energy storage to the power grid and ac and/or dc microgrids, modeling and control of power electronic systems, and Hardware in the Loop (HIL) verification strategies.  Dr. Herrera received the Ohio Space Grant Consortium (OSGC) Doctoral Fellowship during his PhD studies.
