Filtracja zaburzeń przewodzonych w rezonansowym konwerterze do zasilania lamp z diodami LED dużej mocy

This paper presents design process of one-phase 120W switching mode power supply dedicated for luminaires with LED diodes according to EU standards. Technics of detection of electromagnetic emission sources in the SMPS sub-modules as well as methods of reduction of conducted emission level were shown. Conducted emission filter in resonant converter for high power LED lighting applications.
