Flyback power supply from the mains
Polián, Josef ; Kadlec, Josef (referee) ; Huták, Petr (advisor)
This bachelor thesis deals with the issue of switching power supplies. The aim is to design regulated switching power supply that will be powered from the mains. The first part focuses on theoretical knowledge of the switching power supply and describes circuits of TOPSwitch. Another part is the actual design of all circuits. The last part is the actual implementation of switched mode power supply and measurement that verifies its functionality and features.

Discomfort glare of non-uniform luminaires
Polián, Josef ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
Artificial lighting is an integral part of our everyday life. Nowadays, a large number of people spend practically all their productive time in the presence of the artificial lighting system. This places considerable demands on the quality of this artificial lighting system. One of the indicators of the quality of the lighting system is the evaluation of glare. The UGR evaluation methodology is currently used to evaluate glare. However, the UGR rating has its limitations. These limitations include ambiguous assessments of luminaires with non-uniform luminous surface (so - called non - uniform luminaires). This diploma thesis deals with the issue of discomfort glare of non-uniform luminaires. The aim is to make a literature review of this issue. The first part focuses on theoretical knowledge of glare and its evaluation. Another part is an analysis of recent studies on the topic about glare from non-uniform types of luminaires. The last chapters of the thesis deal with own practical evaluation of glare.
