Plenary Speakers

IEEE IEMDC 2017 Plenary Session

Plenary Talk 1: Tuesday May 23, 2017 Symphony I&II Ballrooms 1:00-1:45PM

Speaker: Mr. Lynn J. Petersen, Program Officer, Office of Naval Research (ONR)

 Title:  Navy Application of Silicon Carbide (SiC) Wide Bandgap (WBG) Semiconductors Enabling Future Power and Energy Systems

Abstract--Silicon carbide power devices switching at greater than 100 kHz enable new benchmarks in power converter performance. These converters will enable power systems where all the sources and loads are connected by converters. These new systems are multifunctional and highly-integrated. However, their realization requires research in areas such as: advanced power electronic control across many converters, concepts for distributed storage, and active filtering across many converters.

Biographical Sketch

   Mr. Petersen graduated from the United States Naval Academy, Annapolis, MD with a BS in Mathematics in 1986 and was commissioned an Ensign in the United States Navy. Selected for lateral transfer to the Engineering Duty Officer program, he received his MS in Mechanical Engineering from the Naval Postgraduate School, Monterey, CA in 1994. Following Active Duty, he was employed by the Naval Surface Warfare Center, Carderock Division, Annapolis, MD as an Electrical Engineer. From 1998-2002, he led several projects supporting Navy Electric Drive and authored several papers and reports on electrical propulsion, conversion, generation and distribution. In October, 2002, he was detailed to the Office of Naval Research (ONR), and in May, 2006 he was hired by ONR and served as the ONR S&T rep to the Electric Ships Office, PMS 320. In November, 2008, he was recalled to Active Duty with assignment as the Deputy Director, Electric Ships Office, PMS 320, where he served from 2008-2012. While in that assignment, he was promoted to the rank of Captain in 2009, later retiring from the military in 2016 following 30 years of service in the Navy.

From 2012-2014, he was the Navy’s Director for Systems Engineering in the Deputy Assistant Secretary of the Navy (DASN) office for Research, Development, Test and Evaluation (RDT&E). Following his return to ONR in October 2014 from DASN (RDT&E), Mr. Petersen serves as a Program Officer at ONR where he leads basic research in power electronics, electromagnetism, and adaptive controls and applied research in machinery controls, Silicon Carbide (SiC) Wide Bandgap (WBG) semiconductor applications and Medium Voltage Direct Current (MVDC) power distribution systems.

He is married to Alena and they have two adult children.  He is a member of IEEE, American Society of Naval Engineers and the Materials Research Society. He and his wife are active in their church and Gospel singing.


Plenary Talk 2: Tuesday May 23, 2017 Symphony I&II Ballrooms 1:45-2:30PM

Speaker: Dr. Larry Williams, Director of Product Management, ANSYS Inc.

Title: Breakthrough Design Innovation through Simulation

Abstract--Electric machines are being used in more and novel applications throughout the world driven by the need for greater power efficiency in transportation, aerospace and defense and industrial automation.  In the US industrial sector, over 40 million electric motors convert electricity into useful work in manufacturing operations. Industry spends over $30 billion (US) annually on electricity dedicated to electric motor-driven systems that drive pumps, fan and blower systems, air compression and motion control. Globally, 42% of all electricity is used in power industries where two-thirds of this is consumed by electric motors, equivalent to an overall of 28% from global electric energy consumption.

In this plenary talk, we will show how engineers design electric machines and associated drives using advanced physics-based simulation to deliver greater performance and efficiency.  You will see that superior design can be delivered using advanced engineering simulation and high-performance computing leading to breakthrough innovation by both large corporations and small start-ups.  A virtual machine design flow taking into account electromagnetics, thermal effects, and mechanical stress and vibration allows engineers to go beyond the traditional and try new ideas without the tedious and expensive building of multiple prototypes. 

Industry examples will be highlighted that show how high-performance computing (HPC) can be leveraged to fully explore motor designs, how system simulation linked to 3D electromagnetic simulation can optimize both the drive and machine, and how companies combine product simulation with hardware emulation to build drive systems before any electric motor has ever been built.

With the present trend of global industrial automation, the application of electric drive systems (including power electronics and drive control) is expected to grow rapidly in the next decade. Hybrid and Electric vehicles for example, can significantly contribute to reducing emissions by employing power electronics and microprocessor control to drive electric motors.  Including powerful simulation in the design process creates new opportunities for motor and drive designers to innovate more efficient, high-performance systems over the entire vehicle drive cycle. 

In the face of global competition, electric machine manufacturers, like manufacturers in most industries, are searching for ways to reduce cost, optimize designs and deliver them quickly to market. Companies adopting advanced simulation hold a competitive edge in the marketplace. The ability to predict design performance with simulation software without the time and expense of constructing multiple prototypes plays a significant role in creating this competitive advantage.

Dr. Larry Williams is Director of Product Management at ANSYS Inc., Electronics Business Unit.  He is responsible for the strategic direction of the company’s electrical and electronics products, including the High Frequency Structure Simulator (HFSS) and Maxwell finite element simulators.  Dr. Williams is an expert in the application of electromagnetic field simulation to the design of antennas, electromagnetic devices, and high-speed electronics.  He has over 20 years’ experience in the fields of electromagnetics and communications engineering, has delivered technical lectures internationally, and has published numerous technical papers on the subject.  He and his co-authors won the prestigious H.A. Wheeler Prize Paper Award in the IEEE Transactions on Antennas and Propagation, 1995, and the best paper award at DesignCon 2005.  He serves on the UC Irvine Henry Samueli School of Engineering Dean’s Advisory Board and on the California State Polytechnic University Electrical Engineering Department Advisory Board.

Dr. Williams held various senior engineering positions in the Engineering Division of Hughes Aircraft Company, Radar Systems Group, where he was responsible for hardware design and development of advanced active phased array radar antennas, array element and aperture design, associated microwave subsystems, and antenna metrology.

He received his Masters, Engineers, and Ph.D. degrees from UCLA in 1989, 1993 and 1995, respectively.
