Senior Technical Leader of EMC for Ford Motor Company
Keith Frazier serves as Senior Technical Leader of Electromagnetic Compatibility for Ford Motor Company responsible for oversight of all EMC design of Ford automotive products worldwide. His interests include system/subsystem design and analysis for EMC. Between receiving his BSEE from Purdue University in 1976 and joining Ford in 1990, Keith served as an EMC and TEMPEST design engineer for various automotive and aerospace firms including GM, Lockheed, and Magnavox Government Electronics. He is a Life Senior member of IEEE and has authored and presented multiple technical papers and presentations at regional and international symposiums. Keith has authored and co-authored multiple SAE and ISO immunity standards as an active member of the USTAG to CISPR D and ISO TC22/SC32/WG3 international standards committees. In 2008, Keith served as Technical Papers Co-chair for the 2008 IEEE EMC Symposium held in Detroit, Michigan. In the fall of 2023, he was elected member at large of the EMC Society’s Board of Governors and Officers at Large for 2024-2026.
Talk 1: Impact of Electric Vehicles on AM Radio Reception
There is considerable controversy regarding the impact on AM radio reception from electric powertrain sourced EMI. Viewpoints span not only on the technical challenges of managing EMI levels but also the importance of AM radio to the general public. This talk covers the basic physical concepts of AM radio reception in automotive applications in addition to review of the dominant coupling mechanisms between the vehicle’s receiving antenna and its electric powertrain. With that basic understanding, potential mitigation strategies are reviewed. The customer impact is also explored leveraging a variety of sources of data.
Talk 2: RF Radiated Emissions from Electric Vehicles – Regulatory Challenges
Unlike internal combustion engines, electric powertrain in automotive applications pose much greater challenges in meeting regulatory requirements with respect to far-field radiated RF emissions. This talk will review the basic physical mechanisms of the EV powertrain that contribute toward RF emissions from the vehicle. Various mitigation techniques are summarized along with the engineering tradeoffs they create. Current and future regulatory requirements are also reviewed.
Talk 3: RF Immunity Impact on Electric Vehicle Charging from Amateur Radio Usage
Amateur radio enthusiasts include those that install this equipment on cars and trucks. While OEMs have traditionally designed their vehicles to be immune from the use of this equipment, electric vehicles pose a unique challenge when the vehicle is being charged. This talk will focus on the unique physical mechanisms that impact vehicle charging during amateur radio usage and the potential mitigating options to manage it.
Talk 4: EMC and SI Challenges with SerDes Camera Systems for Automotive Driver Assisted Technologies
Road safety has vastly increased due to continued development in Automotive Driver Assisted Systems (ADAS). A critical element of these systems are high resolution digital cameras. To facilitate high data transfer between the camera and the ADAS electronic control unit, serial/deserializer (“SerDes”) communication links are used, which primarily consist of coaxial cable interconnects. This talk will focus on the challenges in using SerDes in an automotive environment with special focus on required shielding performance. The talk includes a review of current USCAR (The United States Council for Automotive Research) standards and needed future improvements.
