Design and fabrication of a device controlling the important parameters of the aquarium based on the selected microcontroller
Cagáň, Adam ; Levek, Vladimír (oponent) ; Háze, Jiří (vedoucí práce)
This master’s thesis describes design of the system, which automatically regulates water temperature in aquarium and measures water hardness. There is performed thermal analysis of specific model of aquarium, which defines required heat power. Based on this power Peltier module and heat exchangers are selected, that are part of designed heat pump. Thesis describes design of control unit based on ESP32-S3 microcontroller and complementary power supply circuit for Peltier module and uninterruptible power supply for microcontroller. Subsequently, there is designed web user interface running on Raspberry Pi 4B, which allows user to change desired water temperature, lighting interval and display measured water parameters.

A Design and Development of a Universal Power Supply for Laptops in Contemporary Motor Vehicles
Cagáň, Adam ; Levek, Vladimír (oponent) ; Šťáva, Martin (vedoucí práce)
This thesis deals with design of DC power supply with adjustable output voltage in range of 15 to 30 V, working in buck-boost topology. Thesis explains selection of buck-boost controller integrated circuit and calculation of values of external components. Designed converter is supplied with overvoltage, overcurrent, and reverse voltage protection circuit. Final circuit is equipped with microcontroller, display, and rotary encoder, which make it easily operable. Further, there are compared parameters of the device achieved in simulation and in practice.

Cagáň, Adam
This thesis deals with design of DC power supply with adjustable output voltage, workingin buck-boost topology. Thesis explains selection of buck-boost controller integradet circuit and calculationof values of external components. Designed converter is simulated in LTspice software,where parasitic properties of used components are included. There are summarized parameters ofconverter in different working states. Further there are mentioned planned expansions of converter,including microcontroler integration with user interface.
