Laboratory Switching Power Supply
Šneidr, Radim ; Petržela, Jiří (referee) ; Šebesta, Jiří (advisor)
The topic of my bachelor´s thesis is a solution to a laboratory switching power supply, look at their benefits, disadvantages and characteristics in terms of EMI. The aim this work is also to design the concept of two outputs switching supply with monolithic circuit, LM2576 with the inclusion of a current limiter and implementation of a test version which will use basic measuring. Further, design a general scheme and the mechanical solution of a power supply including measuring modules. Design layout of printed circuit, complemented with thorough testing.

Adjustable switching power supply
Vyroubal, Rostislav ; Urbanec, Tomáš (referee) ; Baran, Ondřej (advisor)
The aim of this bachelor’s thesis is to create a summary of the convertors, their principles, and to propose the convertor with specific parameters. The printed circuit board is designed for this convertor. Designed convertor is manufactured. Its specific parameters are measured and compared with theoretical parameters. A heatsink is designed for this convertor.

Analysis of switched-mode LED drivers
Stehlík, Ota ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
The aim of this thesis is to design, produce and verify the operation of two different LED drivers for automotive industry, which controls the ultra-bright white LEDs. At the beginning of a brief introduction explaining the principle of operation of LEDs. Furthermore theory describes the functions of all three basic drivers involved as buck, boost and buck-boost. Based on the requirements are selected ICs suitable for this implementation, theoretically described their block diagrams including the individual diagrams and eventually these samples are made, revived and measured their parameters.

Two-quadrant switching current source for inductive loads
Húsek, Jan ; Chmelař, Milan (referee) ; Hanák, Pavel (advisor)
This master`s thesis deals with design and realization of two-quadrant switching current source for inductive loads. Output current adjustable range is 0 – 1A. Selected topology enables change of current direction. Current supply is made with TDA8920 integrated circuit. Thesis also contains basic information about switching supplies and coils.
