Joanna McLellan of EMC Productivity

Abstract:

Electromagnetic Compatibility issues are created by poorly designed transmission lines. As an example, we examine the current flows and energy pathways in an automotive eMotor three phase power transfer. We first review transmission line theory and propose a quick and easy way to determine if a specific transmission line is likely to cause an EMC issues. Then alternative transmission line constructions are discussed to provide lower cost and lower emissions alternatives to the industry standard three orange coax cables. 

Biography:

Joanna McLellan holds a MSEE from Georgia Tech and a BSEE from Florida Tech. She was employed as an electrical engineer for over forty years and has now been a consultant for eight. She has discovered the fastest and most reliable way to resolve EMC issues is to train the
engineering team first. She trains the mechanical, system, and electrical engineers along with the technicians, supervision, and PCB layout personnel as a group making EMC a team sport and creating an environment of success.

She is a member of the IEEE, IEEE EMC Society, IEEE Senior Member, IEEE EMCS SDECom, Eta Kappa Nu engineering honor society, SAE, SAE EMI Task Force, ISO TC22/SC3/WG3 USTAG, and CISPR/D USTAG meeting participant. She is also a past member of the IEEE EMC Society board of directors.

Joanna’s engineering career started in Houston, Texas, as a test engineer for Texas Instruments. She then joined Burroughs in Plymouth, Michigan, and moved into product design. Later she moved to United Technology Automotive designing early multiplexed communication modules for BMW and others. She also worked for Siemens, Harman Becker, TK Holdings (formerly Takata), Kostal. In 2016 she retired from Hella and now provides EMC and EMI training and issue mitigation.  Seeking additional technical challenge she gained an iNARTE Master EMC Design
Engineer certification and started consulting in 2012.

She lives in Holly, Michigan, with her husband Dave McLellan and their dog, Dora, a 15 year old Vizsla.
