February Meeting
Joint with the IAS Chapter

Cy Harbourt
General Electric

Harmonics from Pulse Width Modulated 
Converters

Walter Hill, originally scheduled to present 
this talk, will not be available. Cy 
Harbourt, a joint author, with Mr. Hill, of 
a paper with this title, has graciously 
agreed to step in.

Abstract: 
Even two level PWM sources with low harmonic 
voltage and current distortion 
characteristics can affect a plant power 
system in such a way that voltage sensitive 
electronic equipment is adversely affected. 
It is unwise to feed PWM sources and 
sensitive electronic equipment from the same 
substation transformer. The resulting 
voltage distortion is time consuming to 
troubleshoot and expensive to fix. 
Additional filtering is needed to stop the 
unwanted harmonic frequencies that emanate 
from PWM sources from interfering with the 
operation of sensitive electronic equipment 
such as gas burner controls, robots and 
assembly line sensors typically used in the 
automotive industry.

The paper will describe the generation of 
voltage and current harmonics of two level 
PWM inverter sources. The level of these 
harmonics were measured before the 
application of a passive filter and will 
serve as a guide as to the effectiveness of 
the passive filter in minimizing the level 
of voltage and current harmonics.

About the Speaker

VMS Activities

Meeting Report
January saw the first joint meeting between 
the Shenandoah Section of ASHRAE and the 
Virginia Mountain Section of IEEE. The 
meeting was also, to the best recollection 
of those present, the first IEEE section 
meeting to be held at the Virginia Military 
Institute. Howard Arthur, VMI mechanical 
engineering and ASHRAE section chair, began 
the evening by welcoming the approximately 
60 guests to VMI. He introduced David 
Livingston, VWCC and IEEE section chair, who 
then introduced the evening's speaker, Jan 
Helge Bhn of the mechanical engineering 
department at Virginia Tech. Jan Helge began 
his talk by providing the motivation for 
efforts in rapid prototyping. These include 
much shorter product design cycles and 
improved final designs. By coupling 
computer-aided design with hardware to allow 
these models to be realized in nylon, ABS 
plastic, or fiber-reinforced thermoplastic, 
physical models of the design can be rapidly 
and inexpensively created. With the model in 
hand, tests and experiments can be conducted 
to determine whether modifications or design 
improvements are needed. The idea in rapid 
prototyping is this: By utilizing rapid 
prototyping and several short design cycles 
in sequence, the final design will be better 
and be achieved more quickly than if the 
design process is confined to analytical 
tools and computer-aided design in one 
longer design cycle. There is no substitute 
for having a physical model to test. Dr. 
Bhn provided information on several 
competing technologies in this area-
stereolithography, laminated object 
manufacturing, selective laser sintering, 
and fused deposition modeling. The Rapid 
Prototyping Laboratory at Virginia Tech, 
which Dr. Bhn directs, employs fused 
deposition modeling. Dr. Bhn's research 
includes the development of software to 
speed the deposition process by a factor of 
40. Also of interest is research in fiber-
reinforced thermoplastic. The goal here is 
to be able to control the orientation of the 
fibers throughout a part under fabrication. 
If this were possible, the mechanical 
properties of a particular part could then 
be optimized for that part's shape and 
function. Dr. Bhn's research has 
application in real virtuality, medicine 
(e.g. brain surgery), and in rapid tooling. 
Ed Wheeler, VMI electrical engineering and 
IEEE section vice-chair, thanked Jan Helge 
for his talk and presented him with a 
certificate of appreciation from the IEEE 
Virginia Mountain Section. The reader may be 
interested to know that on page 138 of the 
January, 1999 IEEE Spectrum there appears a 
note which mentions a future spectrum 
article in this area. This article will 
explore the topic of solid free-form 
fabrication (SFF)

IEEE CAREER WORKSHOP

The IEEE Virginia Mountain Section is still 
considering organizing a career workshop. It 
would be a supplement to the services 
offered by company outplacement services, 
and would be targeted specifically toward 
engineers and other technical professionals. 
It would cover psychological aspects of non-
voluntary job change as well as practical 
measures for obtaining a new job. Among the 
topics would be what IEEE has to offer in 
assistance.

If you or anyone you know are in a position 
to need such information in the near future 
or anticipate a more distant need and would 
be interested in such a workshop, please 
contact Dan Jackson, Virginia Mountain 
Section Professional Activities Chairman, at 
(540) 774-0484, or email to 
d.jackson.ieee.org.

IEEE & Teachers = Help

K-12 Students Learn Technology

Piscataway, NJ, 29 January, 1999 -- Fifteen 
members of the IEEE Pre-College Education 
Coordinating Committee (PECC), a cross-
section of engineers and educators, recently 
developed a framework for an IEEE pre-
college education initiative. The framework 
was developed after the committee 
brainstormed ways in which the IEEE and the 
engineering community can collaborate with 
teachers to foster innovative teaching 
strategies among K-12 science, math, and 
technology teachers.

Formed in October 1998 at the Technological 
Literacy Counts workshop in Baltimore, MD, 
the PECC is one of the few IEEE committees 
that actively recruits non-engineers. Pete 
Lewis, Educational Activities Staff 
Director, contends, "It's important that the 
IEEE take an active role in enhancing the 
technological literacy of K-12 students. We 
can only do so by listening to the 
educational needs of those on the front 
lines, the teachers themselves."

In a round-table discussion format, 
participants sought to answer the following 
questions:  In this rapidly growing 
technology age, WHAT tools/resources do K-12 
educators need in order to most effectively 
teach their students science, math, and 
technology subjects?  As the world's 
largest technical professional society, HOW 
can the IEEE, and the engineering community 
at large, help teachers foster technological 
literacy among their students?

A participating and appreciative eighth-
grade science teacher from Oklahoma said, "I 
am so glad the IEEE is breaking out of the 
'box' and reaching out to teachers." In the 
coming months, the IEEE will form a specific 
action plan for its pre-college education 
initiative. For more information, contact 
Barbara Stoler, IEEE Educational Activities, 
445 Hoes Lane, PO Box 1331, Piscataway, NJ, 
08855-1331; e-mail: b.stoler@ieee.org.

The IEEE is the world's largest technical 
professional society, serving the interests 
of more than 330,000 members in the 
information and electrotechnology 
communities in approximately 150 countries. 
In keeping with its "Networking the World" 
slogan, the IEEE helps to foster 
technological innovation, enable members' 
careers, and promote worldwide professional 
community.

IEEE TEAMS UP WITH A UNIVERSITY FOR PILOT 
PROGRAM OF WEB-DELIVERED COURSE

PISCATAWAY, NJ, 28 January, 1999 - The IEEE 
has created an alliance with the Department 
of Electrical and Computer Engineering at 
the University of Illinois at Urbana-
Champaign (UIUC), Urbana, IL, to offer a 
web-delivered course on antennas and 
propagation.

This four-week course, designed to serve as 
a refresher for practicing engineers, will 
be based entirely on the Internet. Classes 
run from 1 April 1999 through 30 April. 
Registration ends 31 March 1999. Course 
capacity is limited to 30 students.

The course will provide learners with an 
analytical and intuitive understanding of 
antenna physics, expose them to antenna 
computer-aided design software, and 
introduce them to a variety of antenna 
structures of practical interest. The course 
will also cover recent developments in the 
wireless and personal communication systems. 
Those intending to register are expected to 
have a basic knowledge of electromagnetic 
wave theory outlining the general plane wave 
solution of Maxwell's equations, phenomena 
involving reflection and transmission of 
plane waves, transmission lines, and 
impedance matching techniques. Students who 
successfully complete the course will be 
awarded 3.6 IEEE Continuing Education Units 
(CEUs).

Eric Michielssen, Ph.D. will be instructing 
the course. Dr. Michielssen received his 
Ph.D. from the University of Illinois at 
Urbana-Champaign in 1992. He is an assistant 
professor in the UIUC Department of 
Electrical and Computer Engineering, 
associate director for the Center of 
Computational Electromagnetics, and a part-
time faculty member in the Beckman Institute 
Photonic Systems Group. His professional 
interests are computational 
electromagnetics, photonic systems, high-
speed digital circuits, fast algorithms, and 
stochastic optimization.

For more information about the course 
contents and requirements, and to register 
for the course, go to:
