Abstract

Opisan je rad jednostavnog silaznog DC-DC pretvornika te rad rezonantnog pretvornika. Navedene su prednosti rezonantnog pretvornika. Opisane su vođene i zračene smetnje, najčešći uzroci smetnji kod sklopova napajanja te načini minimizacije istih. Testiran je rad rezonantnog silaznog DC-DC pretvornika te su provedena mjerenja efikasnosti i karakterističnih signala. Opisan je postupak provođenja mjerenja vođenih smetnji i izmjerene su vođene smetnje rezonantnog DC-DC korištenjem LISN-a. Opisan je postupak mjerenja zračenih smetnji i provedeno je mjerenje sprege sklopa i TEM ćeije što je indikativno zračenim smetnjama.

Abstract (english)

Described working principles of simple buck DC-DC converter and resonant power converter. Described advantages of resonant power converters. Described conducted and radiated noise, most common sources of noise in switch mode power supplies and methods for reducing conducted and radiated noise. Tested resonant buck DC-DC converted and measured characteristic signals. Described process of measuring conducted noise and measured conducted noise of said converter. Described process of measuring radiated noise and measured coupling between converter and TEM cell which is indicative of radiated noise.
