Izrada istosmjernog uzlaznog pretvarača 12V/ 18V; 20W upravljanog s pomoću UC3843

A 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.
