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.

Universal Tester of Tyco Fire panel
Vítek, Ladislav ; Kalina,, Emil (referee) ; Šteffan, Pavel (advisor)
This work is aimed on design of a device for testing of fire detectors and various components of fire detection system, communicating with the fire panel over a fire bus or a loop. The device generates voltages, supplying the detectors, as well as communicating over the bus generating communication waveforms and performing detection of responses measuring voltage and current on the connection. The loop signal is processed by the developed unit and data or result sent to a PC utilizing USB or RS232 connection. All the parts of the equipment are galvanically isolated to the loop circuit.
