20.500.12556/RUL-107707 Tokovni vir za napajanje LED svetil na osnovi integriranega vezja TPS92610-Q1 LED power supply based on the TPS92610-Q1 integrated circuit V diplomskem delu je opisan postopek izdelave vezja za krmiljenje svetlečih diod z uporabo integriranega vezja proizvajalca Texas instruments. Vezje vsebuje časovnik za uravnavanje svetilnosti LED diod, testne točke za meritve ter elemente Za vklop/izklop diagnostičnih in ostalih funkcij. Uravnavanje svetilnosti LED diod je omogočeno z vgrajenim ali zunanjim časovnikom. Na začetku je opisana teorija zgradbe in delovanja LED diod, delovanje čipa za krmiljenje LED diod in vgrajene diagnostične funkcije. Sledi opis postopka določanja vrednosti elementov izbranega linearnega regulatorja, s katerim nastavimo pravilno delovanje diagnostičnih funkcij in ustrezno krmiljenje LED diod. Po določenih vrednostih osnovnih elementov sledi izbira elementov za izboljšanje delovanja vezja, potek risanja sheme in tiskanine vezja s programom Altium designer, simulacija vezja v programu Pspice in primerjava z meritvami izdelanega vezja. The diploma thesis describes the process of manufacturing a power supply for LEDs using an integrated circuit made by Texas Instruments. The circuit contains a timer for adjusting the brightness of the LEDs, test points for measurements, and lements for turning on / off diagnostic and other functions. Adjusting the brightness of the LEDs is enabled with a built-in or external timer The physical background of LED operation is described followed by an overview of the TPS92610-Q1 integrated circuit and its built-in diagnostic functions. Next,the procedure of choosing the element values that result in the desired behavior of the ciruit is described. Several improvements are introduced into the initial circuit. The procedure for drawing the schematic and the PCB in Altium Designer is described. The circuit is simulated with Pspice and the results are compared with the measurements of the manufactured circuit. svetleče diode časovnik integrirano vezje LEDs timer integrated circuit true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-05-15 14:08:31 2019-05-15 14:08:31 2022-08-19 03:50:40 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 45941 Tominc_Mitja_-_Tokovni_vir_za_napajanje_LED_svetil_na_osnovi_integriranega_vezja_TPS92610-Q1.pdf Tominc_Mitja_-_Tokovni_vir_za_napajanje_LED_svetil_na_osnovi_integriranega_vezja_TPS92610-Q1.pdf 1 A6A8A49CCF988E3969E855506C5D7BF2 5784438205176a5a295cd17e6b70c6b6953ad6375bdac0be7cf6d6840d75f3c8 7e995f41-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118590 Fakulteta za elektrotehniko 0 0 0
