Interferentzia elektromagnetikoaren azterketa potentzia-elektronikako sistemetan Si-WBG trantsizio teknologikoaren testuinguruan

Abstract

This research project has analysed the effect of electromagnetic interference (EMI) on power electronics systems, as well as the effect of the transition from silicon-based devices to WBG-based devices. The main goal has been to identify the parameters that have an impact on EMI generation and propagation. A test bench has been designed to analyse the effect of varying these parameters on the main signals (currents and voltages) in the time and frequency domain. The results obtained are intended to provide the electronic designers with a tool to ensure that their designs comply with EMC regulations, as well as maximising energy efficiency.

Ikerketa honek potentzia-elektronikako sistemetan sortzen den interferentzia elektromagnetikoa (EMI, Electromagnetic Interference) aztertu du, baita silizioan oinarritutako gailuetatik banda zabaleko erdieroaleetan (WBG, Wide Band Gap) oinarritutako gailuetara igarotzeak duen eragina ere. Helburua EMIaren sorkuntzan eta hedapenean eragiten duten parametroak identifikatzea izan da. Saiakuntza banku bat diseinatu da parametro hauen aldakortasunak denbora- zein maiztasun-eremuko seinaleetan duen efektua aztertu ahal izateko. Lortutako emaitzekin elektronika-diseinatzaileei potentziabihurgailuen diseinurako tresna bat eman nahi zaie; horren bitartez, energia-efizientzia maximoa lortzen saiatzeaz gain, EMI-sorkuntzaren eta bateragarritasun elektromagnetikoko (EMC, Electromagnetic Compatibility) araudiaren betekizunei erreparatu ahal izango diete.
