Uporaba simulacij za predvidevanje elektromagnetnih prevodnih emisij stikalnega napajalnika

ČEPON, ANA (author), Trontelj, Janez (mentor)

V nalogi je predstavljen postopek razvoja segmenta vezja s poudarkom na prevodnih emisijah, ki spadajo na področje elektromagnetne skladnosti. Bistvo naloge je prikaz rezultatov simulacij v primerjavi z realnimi meritvami v merilnem laboratoriju. Na kratko je predstavljeno področje elektromagnetne skladnosti, realni primeri težav in uporabljeni standard. V nadaljnjem delu je predstavljen splošen pomen simulacij. Opisano je osnovno delovanje stikalnega pretvornika, njegovo prilagajanje napetostnih nivojev, težave z elektromagnetno skladnostjo, ki se pri njem pojavljajo, ter nekaj možnih rešitev za njihovo odpravljanje. Predstavitvi pretvornika sledi uvod v simulacijska okolja. V zadnjem delu naloge je opisano še naše delo in komentarji rezultatov.

Abstract

This work presents the process of developing the circuit, with the emphasis on conducted emissions, which fall under the scope of electromagnetic compatibility. The focus of this study is to present a comparison of the simulation results and real measurements performed at the professional measurement laboratory. A short overview of the field of electromagnetic compatibility, real examples of problems and the applicable standard are given. The overall importance of simulations is discussed. The basic operation of the switching regulator is described and how such regulator adapts the voltage levels. Problems with electromagnetic compliance, which occur in these regulators, as well as some possible solutions are presented. Description of the regulator is followed by an introduction to the simulation environment. The thesis is concluded by description of our work and comment of the results.
