Design of the boost converter; 2V/ 18V; 20W , controlled by IC UC3843

Izrađena je maketa uzlaznog pretvarača napona upravljanog integriranim krugom UC3843N. Opisane su karakteristike te navedeni unutarnji podsklopovi integriranog kruga. Prije izrade makete napravljena je analiza rada. Pretvarač je testiran u laboratoriju. Uočeni su nedostaci pri testiranju pretvarača. Početna shema uspoređena je s više shema u kojima je korišten navedeni integrirani krug. Uspoređivala se topologija pretvarača i vrijednosti zadanih komponenti. Provedenom analizom dobivena je nova shema istosmjernog uzlaznog pretvaračaA model of the DC-DC boost converter, controlled by UC3843N, was made. The features and the internal sub-assemblies of the integrated circuit are described. Before the model was made, a theoretical analysis of the work is done. The converter was tested in the lab. There are encountered shortcomings in the inverter testing. The initial scheme was compared with the multiple schemes where the same integrated circuit was used. The topology of the inverter and the values of the default components have been compared. A new straight ascending converter scheme has been obtained
