20.500.12556/DKUM-80382 Modeliranje in simulacija visoko napetostnih vezji v električnem pogonskem sklopu s poudarkom na elektromagnetni kompatibilnosti magistrsko delo Modelling and simulation of high voltage circuit architecture in electric powertrain with focus on electromagnetic compatibility Avtomobilska industrija vse bolj stremi k hibridni ali popolni elektrifikaciji prevoznih sredstev. Nekatera podjetja so objavila, da s priˇcetkom novega desetletja ne bodo veˇc prodajala avtomobilov z motorjem na notranje izgorevanje. Najpomembnejˇsi cilji pri naˇcrtovanju novih elektriˇcnih pogonov so zmanjˇsanje pogonskega sklopa ter viˇsji izkoristek in zmogljivost. Integracija oziroma poslediˇcno zmanjˇsanje celotnega pogonskega sklopa pomeni krajˇse medsebojne razdalje med elektriˇcnimi komponentami. Vzrok katerih je lahko morebitno poveˇcanje elektromagnetnih motenj. Nov produkt ne more priti na trg, ˇce ne izpolnjuje predpisov v skladu s elektromagnetno zdruˇzljivostjo (EMC). V magistrski nalogi je predstavljeno celotno modeliranje in simulacija parazitnih paramet- rov in njihov vpliv na celoten model sistema. Parazitni parametri so pridobljeni za moˇcnostne kable, ˇsestfazno bakreno vodilo, leˇzaj in sinhronski motor s trajnimi mag- neti, z uporabo tridimenzionalnih elektromehanskih modelov z metodo konˇcnih elemen- tov. Pridobljene upornosti, kapacitivnosti, lastne in medsebojne induktivnosti so im- plementirane v kontrolni model sistema. V veˇcini primerov so ti elementi zanemarjeni v simulacijah, zato njihova vkljuˇcitev v model pripomore k pridobitvi bolj natanˇcnih rezultatov ob primerjavi z meritvami. Boljˇsi rezultati privedejo do natanˇcnejˇsih informacij o sistemu, kot so: prenihaji, oscilacije, harmonski spekter, elektromagnetne motnje, maksimalne delovne toˇcke, licitacije sistema itd. Na podlagi teh informacij je lahko raziskan sistem modificiran in optimiran pred zaˇcetkom prototipne ali testne faze projekta. Rezultati, predstavljeni v tej magistrski nalogi, nakazujejo, da je razvita metoda in inte- gracija v model primerna za predvidevanje licitacij in problemov sistema. Z opravljen- imi meritvami elektromagnetnih motenj je lahko opravljena validacija pogonskega sklopa ter nadaljnja nadgradnja modela za pridobitev rezultatov znotraj ˇzeljenih odstopanj. The vehicle industry is heading towards hybrid or fully electrified mobility. Some car manufacturers have stated that with the beginning of the new decade, they will not sell any more cars with conventional combustion engines. The most important requirements for electric machines are downsizing, higher efficiency, and power densities. Downsizing creates smaller distances between electric components, which can lead to higher electro- magnetic interference. Therefore, a new product cannot come to the market unless it satisfies the electromagnetic compatibility (EMC) government regulations. Throughout this thesis, the whole modelling and simulations of the parasitic parameters and their influence on the full system model is introduced. The parasitic parameters are obtained from shielded cables, bus bar, bearing, and IPM motor using 3D electro-magnetic finite element models. The obtained resistances, capacitances, self and mutual inductances are implemented into the control model of the system. Usually those components are left out, therefore, when including them, the system responses become more accurate compared with the measurements. Better responses can provide useful information about the system, such as: overshoots, noise, spectral harmonic components, electromagnetic interference, maximum operating points, back EMF, etc. Based on this, the investigated system design can be optimized before the prototype and testing stage of the project. The results presented throughout this thesis indicate that the developed methodology and integration is suited for anticipating control limitations and issues. With EMI measurements, the system model can be verified and further modified to obtain more accurate results. elektro mobilnost elektriˇcni pogonski sklop elektromagnetna kom- patibilnost (EMC) elektromagnetne motnje (EMI) medsebojni vplivi metoda konˇcnih elementov (MKE) automotive drive-train electromagnetic compatibility (EMC) electromagnetic interference (EMI) coupling effects finite element method FEM true true false [A.
