# Design for Guaranteed EMC Compliance (2 Days)

## Description

Is it possible to design a complex system such as an automotive or industrial control system, computing device, or telecommunications equipment, that is guaranteed to meet all electromagnetic compatibility requirements before the first prototype has been tested? In most cases, Yes! In fact, designing for guaranteed EMC compliance is a more systematic and cost-effective way of ensuring that products won't have problems in the field, as compared to simply testing for EMC compliance after the product is built.

Designing for guaranteed compliance is not a matter of following a set of design rules or sealing everything inside a metal enclosure. It is a systematic process of identifying and evaluating all possible EMC sources, victims and coupling paths within a system as well as coupling between the system and its environment. At first glance, this may sound overwhelming, but designing for guaranteed compliance can usually be accomplished without any impact on product cost or development schedules.

This course leads students through the process of systematically ensuring that their product designs will meet all applicable EMC requirements. Students will learn to identify and utilize the ground structure, control the flow of high and low-frequency currents, identify and characterize potential sources and victims of EMI, control bandwidths, ignore structures and coupling paths that do not contribute to EMC problems, and systematically identify and evaluate structures and coupling paths capable of causing a product to be non-compliant.

It is assumed that students taking this course have a basic understanding of fundamental EMC concepts (for example, students that have completed the Fundamentals of Electromagnetic Compatibility course or the Electronic Systems Design for EMC Compliance course). The focus of the course will be on the application of these fundamental concepts to the systematic evaluation of actual product designs.

## Course Instructor

Dr. Todd H. Hubing is a Professor Emeritus of Electrical and Computer Engineering at Clemson University and Director of the Clemson Vehicular Electronics Laboratory. He and his students at Clemson have worked on the development and analysis of a wide variety of electronic products. EMC design rules can vary greatly depending on whether you are designing high-speed computing equipment, low-cost mixed-signal consumer products or high-power industrial controls; but the basic EMC principles are the same in all industries. By applying these principles in an organized manner, it is possible to review a design circuit-by-circuit to guarantee that any particular EMC requirement will be met. This approach is more effective than the blind application of design guidelines and is the primary emphasis of every EMC design class taught by Dr. Hubing.
