Abstract: [cze] [eng]
Táto diplomová práca sa zaoberá s meničmi pre výkonové LED diódy. Dáva osvetu do oblasti LED svietení, analyzuje jednotlivé typy meničov, ukáže princípy ich funkčností. Ďalej navrhuje možné zapojenia pre tri rôzne napäťové úrovne a výpočty jednotlivých prvkov. Obsahuje výsledky meraní navrhnutých meničov a vyhodnocuje merania. The master‘s thesis deals with DC/DC converters for power LED diodes. Gives an overview of the field of LED lighting technology, analyzes various types of converters and shows their principle of operation. Furthermore presents some possible circuit designs for three different voltage levels and the calculations for each part. As an approval of their functionality the results of their measurements are plotted followed by the data evaluation.
