Kære medlem af EMC Klubben,
Vi inviterer dig hermed til årets sidste EMC-klubmøder.
Møderne afholdes som fysiske møder og på engelsk, så udnyt chancen og invitér din ikke- dansktalende kollega med.
Årets julegave
Som en lille tradition uddeles EMC Klubbens julegave til alle fremmødte i Aarhus og Hørsholm. Samtidig ønsker vi alle en glædelig jul og takker for et godt klubår.
Tid og sted
Mandag den 1. december 2025 kl. 09.00–15.45
Force Technology, Agro Food Park 15, 8200 Aarhus – mødelokale 1
Tirsdag den 2. december 2025 kl. 09.00–15.45
Force Technology, Venlighedsvej 4, 2970 Hørsholm
Tilmeldingsfrist: Torsdag den 27. november kl. 12.00.
Theme
Join us for a day dedicated to electromagnetic compatibility (EMC) in power electronic converters, with a special focus on the supraharmonic frequency range.
Throughout the day, we will explore how noise propagates in converter systems, including the effects of power grid impedance, differential-mode (DM) and common-mode (CM) noise, and closed-loop impedance.
As part of the program, you will also see an EMC demonstrator based on a real product — a modified Grundfos pump. The demonstrator illustrates how emissions above 1 MHz are often not determined by the components in the mains filter, but instead by the mechanical construction of the product. It includes both conducted noise behavior from 150 kHz to 30 MHz and radiated emissions from 30 MHz to 1 GHz using the same physical setup.
You will also hear about practical modeling approaches, including black-box methods for power converter characterization. The program will further cover EMI filter design and lifetime considerations — discussing suitable topologies, material choices, and key factors that influence filter performance and durability.
The event will conclude with a presentation of a newly developed software tool that supports EMI prediction and EMC design in power electronic converters.
Vi ser frem til at mødes!
