Speed regulation of DC motor with Ćuk converter

Rad se temelji na prekidačkom regulatoru napona − Ćukovom pretvaraču, pomoću kojega se regulira broj okretaja istosmjernog motora s permanentnim magnetom. Regulacija je izvedena u programu Matlab. Rad prikazuje ulazne i izlazne valne oblike struja i napona pretvarača, kao i broj okretaja ovisno o izlaznom naponu te objašnjava sam princip rada istoga. Glavni problem, visoka ulazna struja prilikom pokretanja, riješen je implementacijom softverskih komponenti koje su nalik onima u praktičnom svijetu.This paper is based on switching regulator – Ćuk converter, which is used to control speed of DC motor with permanent magnet. Control simulation was made in Matlab. Paper shows input and output characteristics of current and voltage and RPM based on output voltage. It also explains working principle of Ćuk converter. Main problem, inrush current, while starting up converter is fixed by implementing components which are offered by Matlab. Also, those components are very close to the real ones, which are used in industry
