PC Board Design and Layout for Low-EMI Power Conversion

Talk Title: PC Board Design and Layout for Low-EMI Power Conversion Presentation Outline: As a consultant for over 10 years, Kenneth has realized the root cause of many design issues revolves around the circuit board design and how the I/O and power connectors are arranged and filtered. Poor board designs and poor interconnect placement and filtering can result in radiated emissions, radiated immunity, and electrostatic discharge (ESD) compliance failures, among others. Bad designs often result in endless cycles of trial and error mitigation, compliance testing and board spins. This drags out the schedule and is very costly. In the presentation, Kenneth will explain how digital signals propagate in boards as electromagnetic fields. He will also explain how interconnect placement and poor filtering design and layout can affect the EMI performance. Once you understand this, then board stack-up, trace routing, filter design and interconnect placement should become very clear and you should be able to design a low-EMI board the first time! About the speaker: Kenneth Wyatt is principal consultant of Wyatt Technical Services LLC and served three years as the senior technical editor for Interference Technology magazine from 2016 through 2018. He has worked in the field of EMC engineering for over 30 years with a specialty in EMI troubleshooting and pre-compliance testing. He is a co-author of the popular EMC Pocket Guide and RFI Radio Frequency Interference Pocket Guide. He also co-authored the book with Patrick André, EMI Troubleshooting Cookbook for Product Designers, with forward by Henry Ott. He recently completed and released a three-volume “EMC Troubleshooting Trilogy”, which is now available through Amazon. See web for ordering info. He is widely published and authors a monthly column for the Signal Integrity Journal, has blogged for EDN.com for many years, has a monthly column, EMC Bench Notes, for InCompliance Magazine (starting 2024), writes regularly for EEWorld and continues to write for Interference Technology Magazine. Ken is a senior life member of the IEEE and a longtime member of the EMC Society. Virtual: https://events.vtools.ieee.org/m/443500
