Abstract: This webinar is part of a four-part series about EMC with a focus on switched mode power supplies. Although this part is mainly about general measures and how to design a first time pass, this knowledge is basic for understanding the third and the fourth parts, where we finally analyze switched mode power supplies and appropriate mitigations for reduced EMC problems.

The presentation will provide several approaches and design suggestions that can and should be combined. Depending on the state of design, several remedial actions are possible. So, each mitigation has its moment in the design process.

Implementing the right remedial action at the right time can save time and costs otherwise spent on retesting.

The webinar will include a short live session that will reveal that placement can influence the EMI behavior and cause trouble, although everything is done correctly the potential worst case will be shown. In case your mitigations were not enough, and you obtain a first time fail, this part of the presentation gives a short overview of what you can do to improve the EMC performance of your device.

After this presentation, you will have a good overview of the possible approaches for a good design with a focus on EMC

Presenter: Josefine Lametschwandtner, RECOM Power, Inc. Josefine Lametschwandtner is an EMC Engineer with RECOM Power. She has a BS in Science with an emphasis on Electronics and Technology from FH Joanneum and is working towards an MS in Information Electronics from JKU. She is currently the lead EMC Engineer with RECOM Power and has been with the company since 2012. She is responsible for EMC filter development and testing as well as customer consulting around all EMC related issues (filtering for radiated and conducted emissions, PCB layout adjustments, filtering for surge and transient immunity, etc.).

Webinar: EMC Basics, Immunity - Test and Solutions for SMPS
Abstract: This webinar will be focusing on immunity testing of switched mode power supplies (SMPS) including a brief summary of the required standards while providing a greater understanding of the interconnections between them.
 
There are three main types of EMC-immunity tests for power supplies.
  • Transients
  • High frequency signals coupled over capacitive lines and radiated via antennas
  • Various grid power phenomena as well as disruptions caused by an unstable power grid
The aim of this webinar is to leave you with an understanding of both the test procedures and physical phenomena to allow you to be more prepared for immunity tests and certification.

Webinar: EMC Basics, Coupling Mechanism – Part 1

Abstract: This webinar discusses the fundamentals of electromagnetic compliance (EMC) and will mainly focus on the coupling mechanism. It will introduce real-world parasitic behavior of components, and describe the physics phenomena responsible for the effects. Lastly, the presentation will reveal how to cope with these mechanisms and explore different techniques for noise mitigation.
