Application of DC-DC converters in wireless energy transfer systems

Ovaj rad opisuje efikasnost DC-DC pretvarača koji se koristi u bežičnom prijenosu energije. Rad takoĎer opisuje teoretsku podlogu rada pretvarača. U radu su korištena dva modula: XL4015E1 i MP1584EN. Većina rada se sastoji od raznih mjerenja koja su napravljena sa pretvaračima kako bi se odredila njihova energetska potrošnja i efikasnost. Mjerenja su provedena u raznim električnim krugovima koja variraju od jednostavnijih do nešto složenijih kako bi dobili bolji uvid u funkcionalnost pretvarača u raznim okružjima. Rad će pokazati koji pretvarač ima bolju efikasnost i kakva je ona u odnosu na tvorničke tvrdnjeThis paper describes the efficiency of a DC-DC buck converter utilised in a wireless energy transfer circuit. The paper also describes the theoretical background of the way the buck converter operates. Two modules were used in this paper: XL4015E1 and MP1584EN. The majority of the paper cosists of various measurments made with these converters which determine its power expenditure and efficiency. The measurements were made in different electrical circuits which vary from simple to more complex ones to give a better insight of the converters funcionality. The paper will explain which converter has a better efficiency and whether its comparable with claims given by the manufacturer
