Zasnova in izvedba napajalnika

ŠUSTER, TADEJ (author), Žemva, Andrej (mentor)

Diplomsko delo opisuje pot od ideje do izdelka. Izdelek je naprava, imenovana laboratorijski napajalnik, ki je zmožen izmenično napetost iz vtičnice pretvoriti v enosmerno nastavljivo napetost. Laboratorijski napajalnik se uporablja za preizkus in razvijanje vezij. Namen izdelave napajalnika je predvsem poglobitev znanj s področja regulacije napetosti in navsezadnje tudi kasnejša uporaba v domačem laboratoriju. Poudarek naloge je na zasnovi in izvedbi napetostnega regulatorja. Naloga gre čez faze od teorije, zasnove, razvoja do izdelave napajalnika, ki omogoča nastavljivo napetost od 0 do 25 V in nastavljivo tokovno omejitev od 0 do 4 A. Zaključek pa je namenjen predstavitvi težav pri izvedbi in možnih izboljšav.

• Title: Design and implementation of the power supply

Abstract

This thesis describes the path from idea to the product. The product is a device called a laboratory power supply, which is capable of converting the AC voltage from a socket outlet into an adjustable DC voltage. A laboratory power supply is used to test and develop circuits. The purpose of building the power supply is primarily to increase knowledge in the field of voltage regulation and ultimately for later use in a home laboratory. The focus of the thesis is on the design and implementation of the voltage regulator. The thesis goes through the stages from theory, design, development to the implementation of a power supply that allows adjustable voltage from 0 to 25 V and adjustable current limit from 0 to 4 A. The last part of the thesis is devoted to the presentation of implementation problems and possible improvements.
