Tato bakalsk prce pojednv o teorii sp­nanch zdroj. Obsahuje srovnn­ se zdroji tvoenmi linern­mi souÄstkami a struÄnÄ popisuje principy jednotlivch typ sp­nanch zdroj. VÄt­ pozornost je pak vÄnovna zapojen­ blokuj­c­mu, na jeho zkladÄ je v praxi navren konkr©tn­ sp­nan zdroj. Jsou vypoÄteny vechny kl­Äov© souÄstky vÄetnÄ uveden­ dleitch vztah, obzvltÄ transformtoru, tranzistoru, vstupn­ diody a vybrny konkr©tn­ prvky, kter© jsou nslednÄ aplikovny do konkr©tn­ho zapojen­ sp­nan©ho zdroje. Toto blokuj­c­ zapojen­ se ukzalo jako nefunkÄn­. Proto jsem pistoupil k realizaci zapojen­ zvan©mu polomost, kter© bylo mono zrealizovat.This Bachelor´s Thesis is about switch power supplies theory. It contains comparation with power supplies made of linear components and briefly describes principals of each type. Bigger attention is devoted to fly-back engagement, on which´s basic is then in practice designed particular switch power supply. All key components are counted, including initiation of important species interaction, especially of transformator, MOSFET semiconductor triode, output diode, and there are chosen important components, which are subsequently implemented into the particular switch power supply engagement. This blocking engagement turned out to be functionless. That was why I decided to use engagement called half-bridge, which was viable.
