Switching LED drivers
Doležal, Miroslav ; Pavlík, Michal (referee) ; Šteffan, Pavel (advisor)
In this bachelor’s these are three basic typologies of drivers (step down, step up, step up and down output voltage) described. Five specific integrated circuits fulfilling the requirement for supplying LED diodes are selected. The output of this thesis is the design and construction of LED driver for supplying high brightness LEDs with 900 mA constant current.

DC/DC step-up converter with synchronous rectifier
Pospíšilík, Vojtěch ; Feiler, Zdeněk (referee) ; Červinka, Dalibor (advisor)
In the bachelor’s thesis we will deal with the design, optimization and subsequent build of the increasing DC converter with synchronous rectifier. Experimentally we find parameters for which we will make the design. Then we choose a suitable control circuit and calculate the parameters of the converter output elements, which assign specific components. After that we will design the printed circuit board, complete and we will renew the converter.

The Design of Enlargement of Sensor and Control Module of Mobile Robots Named Brontes
Husar, Jan ; Kopečný, Lukáš (referee) ; Florián, Tomáš (advisor)
This bachelor's thesis deals with the proposal of the sensory module and the control of mobile robots named Brontes enlargement. For this purpose a printed circuit board named MX05 was created, which extends its functionality via connection to the control board named LTR001.2. Construction of the board was conducted on the bases of the needs and requirements coming from robot peripherals. The proposal was created containing the control, protection and filtering features. Further, the board was realized and inhabited. Using MX05 creates a great simplification of wiring and there is implied the extension of the original features that are useful not only in robots Brontes.

Templates of DC/DC Converters
Skoupý, Petr ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this thesis is a suggestion and a realization of universal DC/DC convertor with three chips. The first part of this work is focused on the progressive analysis of the power and control part, as function blocks and diagrams. The greatest emphasis is placed on the three circuit wiring for step-down, step-up and inverting convertor. It was necessary to choose the right control circuit, which is available on the market and fulfil all our requirements. Progressive analysis of outer peripheral parts calculations and selecting for the convertor with specific parameters and load characteristic and creation of universal PCB with shouldering is the final realization.
