EMI/EMC in Systems & Facilities
Systems EMC (Electromagnetic Compatibility) involves the control of EMI (Electromagnetic Interference) at the systems, facility, and platform levels (e.g. outside the box.) This two-course provides a comprehensive treatment of EMI/EMC problems in electronic systems. These include industrial controls, semiconductor tools, medical systems, test systems, and more. The emphasis is on prevention through good EMI/EMC design techniques – grounding, shielding, cable management, and power interface design. Please note – this class does NOT address circuit boards issues. Also, military designers may prefer our class on EMI/EMC in Military Systems. Each student will receive a copy of the EDN Magazine Designer’s Guide to EMC by Daryl Gerke and William Kimmel, along with a complete set of lecture notes.
What you will learn:
- How to identify, prevent, and fix common EMI/EMC problems in electronic systems
- Simple models and “rules of thumb” and to help you arrive at quick design decisions (NO heavy math).
- Design impact (by requirement) of various systems EMC specifications
- Good EMI/EMC systems design practices
Who should attend:
- This seminar is directed at personnel who are wrestling with interference/noise problems in electronic systems. The following could benefit from this class:
- Electronics design engineers and technicians
- Systems engineers/integrators
- Test engineers and technicians
- Technical managers and supervisors
- NO prior EMC experience is necessary or assumed.
- Introduction.Interference sources, paths, and receptors. Identifying key EMI threats – power disturbances, radio frequency interference, electrostatic discharge, self-compatibility. Key EMI concepts – Frequency and impedance, Frequency and time, Frequency and dimensions. Unintentional antennas related to dimensions.
- Grounding – A Safety Interface. Grounds defined. Ground loops and single point grounds. Multipoint grounds and hybrid grounds. Ground bond corrosion. Lightning induced ground bounce. Ground currents through chassis. Unsafe grounding practice.
- Power – An Energy Interface. Types of power disturbances. Common impedance coupling in shared ground and voltage supply. Transient protection. EMI power line filters. Isolation transformers. Regulators and UPS. Power harmonics and magnetic fields.
- Cables and Connectors – A Signal Interface. Cable coupling paths. Cable shield grounding and termination. Cable shield materials. Cable and connector ferrites. Cable crosstalk. Classify cables and connectors.
- Shielding – An Electromagnetic Field Interface. Shielding principles. Shielding failures. Shielding materials. EMI gaskets for seams. Handling large openings. Cable terminations and penetrations.
- Systems Solutions. Power disturbances. Radio frequency interference. Electrostatic discharge. Electromagnetic emissions. Includes brief design checklists
