Introduction to Electromagnetics Compatibility Engineering, SC 071
About this Course:
The introduction and hands-on labs to Electromagnetics Compatibility is targeted for participants interested in practical electromagnetic issues such as unwanted radiation, susceptibility, common mode issues, voltage reference issues, shielding, PCB concerns, and Electrostatic Discharge (ESD). These issues are the most common issues that design engineers face for product compliance, and are necessary design concerns to design into products at the beginning of the product design cycle. The class focuses on helping participants understand the issues to help them improve product designs for both a first class product and EMC compliance and certification.
Participants must have working knowledge in calculus based Electromagnetic Physics and Circuit Theory
Who Should Attend:
Electrical Engineering participants in their mid-sophomore year all the way to working professionals who are interested in improving their understanding of electromagnetics for design and compliance.
At the completion of the course, each student will be able to:
- Describe the motivation and need for electromagnetics regulations and modeling
- Describe and identify the components in real world products that make an electromagnetics model, and create the electrical schematic of the coupling paths that produce the model
- Design and test inductors, capacitors, filters, and transmission lines
- Identity and design systems that minimize crosstalk between components and/or systems
- Apply grounding techniques in systems that are appropriate for the noise reduction needed
- Apply shielding techniques and estimate the amount of coupling that will be reduced with proper shielding including:
- Use of differential mode
- Minimizing ground loops
- Using the appropriate number of ground connections
- Using braided or shielded cables as needed
- Proper terminations between cables and systems
- Common mode chokes
- Decoupling capacitors
- Balanced Circuits
- Select and compare printed circuit board strategies to minimize radiated emissions and susceptibility including stack ups, layouts and return paths
- Identify the appropriate regulatory tests that are necessary to ensure their products are within the legal requirements for radiated emissions and susceptibility
