RECOM to Hold EMC Webinar on Emissions of Switched Mode Power Supplies on September 19th, 2022
RECOM will be conducting its third webinar of its four webinar series that will focus on emissions of switched mode power supplies. It will be held on September 19th, 2022 from 9:00 - 10:30 (CET). The first section of this presentation will be more theoretically to explain the basic knowledge of the “generation” of disturbances. This will be followed then by information about several mitigations that can be easily combined.
Attendees will get information about using a PFC and the types available, filtering and its pitfalls, snubber, controlling mechanism, technologies like spread spectrum, along with precautions to be taken when creating the layout.
The seminar shows different approaches to meet the emission requirements using switched mode power supplies. Dependent on the reason of high emission, some mitigations may be more efficient than others, but in the end it won’t be one single mitigation, but a set of remedial actions necessary to meet the requirements.
This seminar contains a life measurement to make it more vivid and to show the effect of common mode noise, caused by the coupling mechanism against a metallic structure and against PE. This can be very tricky, as you very often do not see the “physical” connection, but over parasitics, this coupling mechanism causes problems.
