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.

Verification series of fast-chargers for lead-acid accumulators 12V and 6V
Benada, Tomáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This thesis is an engineering design of an intelligent fast-charger for lead-acid accumulators. It contains calculations of each component. The switching power supply is the mainstay of the charger that makes the charger portable, lightweight and small. The Intelligent fast-charger for lead-acid accumulators charges the accumulator by method of constant voltage with current limitation of 0,5A, 5A, 10A, 50A. 50A current is used in winter during starting of a car, when the battery can´t provide sufficient current. There are three LEDs placed on the front side of the charger reflecting status of the device. The device comprises safety protection for the charger, supply network and battery.
