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.

Dynamic testing of solar cells
Šneidr, Radim ; Hégr, Ondřej (referee) ; Boušek, Jaroslav (advisor)
The content of this thesis is the validation of the method of dynamic testing of solar photovoltaic cells. Testing methods for determining the parameters of the photovoltaic cell replacement scheme has been verified through testing a set of crystalline silicon photovoltaic cells. To accelerate the diffusion capacity measurement and to improve reproducibility of the measurement we propose new method of determining the time constant for diffusion capacitance using a combination of two short pulses. For this method of measurement new scheme for dynamic tester timing has been proposed and implemented.
