20.500.12556/RUL-129026 Preverjanje skladnosti baterijskega polnilnika s standardom CISPR 14 diplomsko delo Checking the compliance of the battery charger with the CISPR 14 standard visokošolski strokovni študijski program prve stopnje Aplikativna elektrotehnika Pri razvoju novega električnega izdelka se proizvajalci vedno srečajo s standardi elektromagnetne skladnosti, bolj natančno z družino standardov CISPR. Gospodinjski aparati ter hišne naprave na splošno imajo zelo stroge predpise, saj se te nahajajo v neposredni bližini uporabnikov kot tudi drugih električnih naprav enakega ter drugačnega tipa, in je zato pomembno, da so te naprave varne in ne invazivne. Dobro testirane in s standardi skladne naprave pripomorejo k boljšemu delovanju naprav, manjšim obremenitvam javnih močnostnih omrežij, boljši uporabniški izkušnji in posledično tudi k večjem zadovoljstvu kupca. V tej diplomski nalogi je na primeru polnilnika baterij prikazan potek preverjanja elektromagnetne skladnosti po standardu CISPR 14. Prikazan je pregled standarda CISPR 14 in vseh standardov elektromagnetne skladnosti, na katere se ta sklicuje. Vsem standardom je podan opis pojava, na katerega se nanaša, in posledično sam razlog za obstoj tega standarda. Bolj podrobno so prikazane tudi zahteve in mejne vrednosti standardov, kot tudi postavitve naprav. Vsakemu standardu je podan tudi prikaz praktične izvedbe ter rezultatov le tega na primeru polnilnika baterij, ki je vse teste opravil uspešno. Ti testi se nanašajo na meritve elektromagnetnih emisij, torej prevodne in sevalne emisije, harmonske tokove ter nihajne napetosti in utripe, ter meritve elektromagnetnih imunosti, torej imunost na elektrostatično razelektritev, sevane elektromagnetne motnje, hitre prehodne pojave, napetostne udare, prevodne motnje ter padce, prekinitve in variacije napetosti. Ob samih standardih pa so podani tudi opisi naprav, ki se jih potrebuje za samo izvedbo meritev. When developing a new electrical product, the manufacturers always encounter electromagnetic compliance standards, more specifically the CISPR family of standards. Household appliances and devices have very strict regulations and requirements, as these are located in the immediate vicinity of users as well as other electrical appliances and devices, therefore it is important that they are safe and non-invasive. Well tested and standard compliant devices contribute to better device operation, lower public network emissions, a better user experience, and, consequently, greater customer satisfaction. This thesis includes electromagnetic compliance testing on a battery charger according to CISPR 14. This thesis includes an overview of the standard CISPR 14 and all the electromagnetic standards to which it refers. All the standards are given a description of the phenomenon to which they refer and, consequently, the very reason for the standards existence. The requirements and limits of the standards, as well as the required layouts of the devices, are also shown in more detail. The practical implementation of the standards and their results are shown in the case of a battery charger, which passed all the tests successfully. These tests include measurements of electromagnetic emissions, such as conducted and radiated emissions, harmonic currents, voltage fluctuations and flicker, as well as measurements of electromagnetic immunity, ie electrostatic discharge, electromagnetic immunity, electrical fast transients, surge, conducted RF immunity, voltage dips, interruptions and variations. In addition to the standards themselves, there are also descriptions of the devices needed to perform the measurements.
