Design for Guaranteed EMC Compliance - 10/18 & 10/19
Students completing LearnEMC open-enrollment courses are eligible to receive IEEE continuing education credit. 0.75 CEUs (or 7.5 PDHs) are awarded for each day of course instruction.
Fundamentals of Electromagnetic Compatibility
Nearly all electronic systems are required to meet electromagnetic compatibility (EMC) requirements before they can be sold or offered for sale. For many automotive, aerospace and industrial systems, electromagnetic compatibility is a product safety issue as well as a product compliance issue. Systems with printed circuit boards that are auto-routed or laid out according to a list of “design rules” do not usually meet electromagnetic compatibility requirements. These systems are likely to require multiple trips to the test lab and expensive "fixes" such as ferrites on cables or extensive shielding.
Product engineers with a basic knowledge of important EMC fundamentals can easily avoid many of the most common design mistakes that result in EMC test failures. This two-day course is designed to introduce these fundamental concepts to circuit designers, board layout professionals, test engineers or anyone with an interest in ensuring that electronic systems meet their EMC requirements. The course stresses the fundamental concepts and tools that electronics engineers can employ to avoid electromagnetic compatibility and signal integrity problems. Students completing the course will be able to make good decisions regarding board layout and system design for EMC. They will also be well prepared for advanced courses in electromagnetic compatibility that require students to have a basic grasp of important fundamental concepts. Course Outline.
Design for Guaranteed EMC Compliance
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.

Power Electronics Design for Electromagnetic Compatibility
This course covers fundamental and advanced design concepts related to the design of power electronic circuits for meeting electromagnetic compatibility requirements. In the morning session, basic power electronic circuit topologies and applications are reviewed with a focus on the fundamental properties of these circuits that result in unwanted conducted and radiated emissions. Noise source models are presented and various noise mitigation options are examined. The focus of the afternoon session is on advanced design concepts including grounding strategies, component selection and placement, and methods for maintaining electrical balance. Active noise cancellation techniques applicable in various situations are also presented. Finally, examples of good and bad power circuit designs ranging from low-voltage DC-to-DC converters to 700-volt electric vehicle motor drives are reviewed. Course Outline
