Computer Program Solves Complex EMC Problems

As part of the curriculum in Donald Sweeney and Roger Swanberg’s new EMC Practical Applications Seminar/Workshop, students will use and then take home a copy of the computer program designed by the instructors that addresses design considerations from component level, through circuit boards, to enclosure level.

“We were using Michel Mardiguian’s book,” Sweeney said, “but he uses graphs for the equations and I always wanted to computerize them. So we did. Now we can predict harmonic content and radiated emissions from loop areas on a circuit board or even on a chip. We can also predict common and differential modes on cables with the computer, then put a cabinet around the board and predict emissions through the penetrations in the cabinet.”

The hands-on seminar/workshop, scheduled for April 14-15 and April 18-19 at the Hilton Hotel in Northbrook, Illinois, provides the step-by-step design process to avoid EMC problems. Attendees may then put their newly acquired knowledge to immediate use in a 45-minute design evaluation of their own product.

Sweeney started his own EMC testing facility over 21 years ago. Now called D.L.S. Conformity Assessment, Inc., it recently became a fully qualified agent of CSA International and now provides product safety testing at its Wheeling, Illinois, facilities for both U.S. and Canadian requirements to CSA, UL, ANSI, FM and other North American standards. It is the first lab to reach this status.
