Design for Automotive EMC Compliance
Today's automobiles are complex electronic systems containing dozens of microprocessors and a variety of RF transmitters and receivers. Automotive components rarely employ shielded enclosures and are subjected to a unique set of EMC tests that can be difficult to comply with unless specific design precautions are implemented early in a product's development. Minor mistakes in the layout of automotive circuit boards can make the difference between a reliable product and a product with severe susceptibility problems. Decisions related to wire harness design and routing can also have a profound effect on a vehicle's electromagnetic compatibility. The course will present overall strategies for vehicle-level design, including component characterization for vehicle-level modeling and system interactions that must be accounted for early in the automotive design process.
This course stresses the fundamental concepts and tools that automotive electronics engineers can utilize to avoid electromagnetic compatibility and signal integrity problems. Students completing the course will be able to make good decisions regarding board layout and automotive system design for EMC. They will also be introduced to tools and techniques for quickly reviewing automotive designs in order to flag potential problems well before the first hardware is built and tested. Course Outline
Automotive Printed Circuit Board Layout
Printed circuit board layout is often the single most important factor affecting the electromagnetic compatibility of automotive systems. Boards that are auto-routed or laid out according to a list of design rules do not usually meet electromagnetic compatibility requirements on the first pass; and the automotive systems relying on these boards are more likely to require expensive EMC fixes. Boards that are "patched" in order to comply with component-level EMC tests, can often be the source of problems that arise during vehicle-level testing.
Proper layout is particularly important in mixed-signal boards (boards with both analog and digital circuits). Recognizing poor design features early in the development cycle can save a lot of time and expense later on. This course stresses the fundamental concepts and tools that board designers must be familiar with to meet automotive EMC requirements. Students completing the course will be able to make good decisions regarding component selection, component placement, and trace routing. In addition, students will have the knowledge and tools necessary to design effective power distribution and grounding strategies for automotive printed circuit boards. Course Outline
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
