Vpeljava metode analize prevodnih emisij po standardu CISPR 25 na podanem vzorcu elektromotorja

KAŠČEK, JAKA (author), Sešek, Aleksander (mentor), Ergaver, Gregor (co-mentor)

V delu na primeru enosmernega brez-krtačnega elektromotorja z vezjem predstavimo postopek priprave modelov in analiz v programskem okolju Ansys Electronics Desktop®, s poudarkom na uporabi reševalnika Ansys HFSS®. Postopek je namenjen simulaciji prevodnih emisij elektronskih komponent za avtomobilsko industrijo po standardu CISPR 25. Postopek se uporablja v obdobju načrtovanja izdelka za zmanjšanje števila potrebnih prototipov za EMC meritve. Poleg tega si lahko s postopkom pomagamo pri odpravljanju visokih elektromagnetnih prevodnih emisijah izdelka. Za doseganje želenega cilja pripravimo 3D model vzorca v reševalniku HFSS®, ki z uporabo metode končnih elementov izračuna matriko S-parametrov modela. To nato uvozimo v okolje Ansys Circuit in ga povežemo z ostalimi deli vezja. Pripravimo in uvozimo tudi SPICE modele krmilnika in tranzistorjev in jih povežemo v vezje. Z uporabo reševalnika Ansys NEXXIM® izvedemo tranzientno analizo pripravljenega vezja ter dobljene rezultate z uporabo programskega okolja Scilab® obdelamo z modelom EMI sprejemnika in primerjamo z izmerjenimi rezultati.

Abstract

This thesis presents the process of setting up models and analysis, on the example of brushless direct current motor with printed circuit board, using Ansys Electronics Desktop® software pack, with the accent on using Ansys HFSS® solver. The process is built for simulation of conducted emissions based on CISPR 25 EMC standard. The process is to be used during the design stages of the product to decrease the number of prototypes necessary for EMC testing. Besides that, it can be used as a helping tool for reducing high value electromagnetic conducted emissions of the product. To achieve the desired goal, the 3D model of the sample is prepared in the HFSS® solver, which calculates the S-parameter matrix, using the finite element method, which is then imported to Ansys Circuit workplace, where it is connected to the other parts of the circuit. The models for driver and transistors are also prepared imported and connected to the circuit. The transient analysis of the prepared circuit is run using Ansys NEXXIM® solver, and the results are then exported and processed through EMI receiver model, running on Scilab software, and compared to the results of measurements.
