Abstract

Rad se fokusira na područje energetske elektronike koje se bavi rezonantnim pretvaračima. Stavlja se naglasak na LLC rezonantne pretvarače koji danas imaju široku uporabu. Opisuje se podjela rezonantnih pretvarača te se posebna pozornost obraća na serijski rezonantni LLC pretvarač s galvanskim odvajanjem. Prikazani su struktura, načini rada i načela projektiranja takvog pretvarača. Na temelju proučene i opisane teorije prelazi se na pretvarač za autonomno napajanje izmjenjivača pogona tramvaja za koji je napravljena simulacija u programskom alatu PLECS. Završni dio rada je metoda ujednačavanja struja u tri faze pretvarača.

Abstract (english)

The paper is focused on the field of power electronics that has to do with resonance converters. Emphasis is placed on LLC resonant converters which are widely used today. The division of resonant converters is described, with special attention given to the series resonant LLC converter with a transformer. The structure, operation modes, and design principles of such a converter are presented. Based on the studied and described theory, the focus shifts to the converter for autonomous power supply of a tram drive inverter, for which a simulation has been performed using the PLECS software tool. The final part of the paper discusses the method of current balancing in the three phases of the converter.
