Driver of high brightness white LED
Tomášek, Petr ; Kubíček, Michal (referee) ; Frýza, Tomáš (advisor)
This document is analysing LED driving with switch power supply from classic electric network 230V/50Hz. First chapter analysis LED diodes function and its fundamental parameters . In the second chapter, there is essential information about electric power supply. Third chapter is analysing switch power supply, including simple techniques, which are not used nowadays. In the fourth chapter, there is analysis of LED driver and circuit design. Fifth chapter is analysing construction of driver and its safety. There i salso information about measuring of parameters of constructed driver.

Driver of high brightness white LED
Tomášek, Petr ; Kubíček, Michal (referee) ; Frýza, Tomáš (advisor)
This document is analysing LED driving with switch power supply from electric distribution network 230V/50Hz. In the first chapter you can find short thesis about electric power supplies. Second chapter contains info about power supplies and their safety and EMC requirements. In the third chapter is analysis of LED. Chapter IV. is dedicated to LED power supply circuit desing and the last chapter is about construction and measuring of parametres of designed power supply.

Comparison of switching LED drivers
Káňa, Vojtěch ; Šotner, Roman (referee) ; Frýza, Tomáš (advisor)
This bachelor thesis describes switching LED drivers and their features. Is chosen and compared five integrated circuit, that one of them will be included in two different topologies. Especially in Buck-Boost and SEPIC configuration. Their characteristics and features will be simulated and designed in suitable software. Made equipment will be tested and compared their achievements properties. For a both of these drivers is required specified conditions as constant output current, input and output voltage.
