20.500.12556/DKUM-86493 Challenges in the EMC standardization of wireless power transfer systems Izzivi v EMC standardizaciji sistemov brezžičnega prenosa energije Charging of electrical and electronic equipment is currently mostly done via conducted connection to an AC/DC power supply unit. However, trends in technology, also driven by issues of convenience for the user, are moving towards wireless power transfer (WPT). A wireless process, in which most of the power is just used for the transfer of energy, includes the usage of a frequency for the power transfer, hence needing resources in the frequency spectrum. As the frequency spectrum is more or less completely assigned to the usage of radio or other services, such as industrial, scientific or medical (ISM) applications, it turns out to be a relatively complex task to actually decide on which frequencies can be used for WPT technology. This paper describes the challenges in the determination of such frequencies in terms of standardization and presents the related consequences. Polnjenje električne in elektronske opreme je večinoma izvedeno preko povezave naprave z izmenično ali enosmerno napajalno enoto. Trendi v tehnologiji, ki jih narekuje vprašanje priročnosti za uporabnika, se premikajo proti brezžičnemu prenosu energije (WPT). Brezžični proces, pri katerem se večina moči porabi le za prenos energije, uporablja frekvenco za prenos energije, zato potrebuje vire v frekvenčnem spektru. Odločitev na katerih frekvencah se bo uporabljala tehnologija WPT, se je izkazala za kompleksno, saj je frekvenčni spekter bolj kot ne dodeljen v uporabo radiju in drugim storitvam, kot so recimo ISM frekvenčni pasovi. Članek opisuje izzive v določitvi omenjenih frekvenc v smislu standardizacije in predstavlja s tem povezane posledice. electromagnetic emissions EMC radiated emissions wireless power transfer inductive power transfer elektromagnetne emisije brezžični prenos energije EMC standardizacija induktivni prenos energije true false true Fakulteta za energetiko Univerze v Mariboru Angleški jezik Slovenski jezik Strokovno delo 2023-12-05 14:07:52 2023-12-05 14:18:08 2023-12-06 03:11:18 0000-00-00 00:00:00 2019 0 0 Str. 11-17 Št. 3 Letn. 12 nov. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-11-01 621.3 1024371036 1855-5748 Challenges_in_the_EMC_standardization_Jaekel_2019.pdf Challenges_in_the_EMC_standardization_Jaekel_2019.pdf 1 787B7B109440A063B841AE9854AA9D45 4972ce66d5c927c71668045ba90e7e1e5a11ede9563e78fedd9e40c8986589b6 8550efba-9370-11ee-add4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174629 https://www.fe.um.si/e-jet/38-2019/1966-november-2019.html 0 8e9b5856-9370-11ee-add4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174630 Fakulteta za energetiko Journal of energy technology 0 0 0
