Design of stabilized dual power supply
Svoboda, Tomáš ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor’s thesis is focused on design and construction of stabilized dual power supply with adjustable output voltage in range 0 – 30 V and adjustable current limit in range 0 – 3 A. Power supply consists of line transformer, switching regulator and subsequent application of linear regulator for better output properties. Measurement of output voltage and current is realized by microcontroller ATmega644, which has optical separated inputs. In this thesis the device is designed and simulated. The design is verified by prototype device and then full construction is done. Construction is tested by measurements, which confirm a proper design.

Controlled laboratory supply
Štibraný, Miroslav ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
Master’s thesis deals with design of laboratory supply with precise voltage and current measuring. At the beginning it presents properties, advantages and disadvantages of linear and switching supplies, based on these facts it chooses a linear type of regulator. The design continues with detailed description of power and control analog and digital circuits. The thesis includes description of taking control over the supply from the front panel or through computer. The last part is devoted to measurement results and to presentation of some static and dynamic parameters of the designed supply.

Precision laboratory power supply
Bartoš, Dalibor ; Šteffan, Pavel (referee) ; Levek, Vladimír (advisor)
The subject of this thesis is a design of a precision dual channel laboratory power supply with output voltage range from 0 to 30 V and adjustable current limit up to 1 A. The proposed solution is based on linear regulators and input voltage switching system to minimize power dissipation. Galvanically isolated channels of the power supply share the same microcontroller that processes the user inputs. Microcontroller code allows the calibration of the device or it’s communication with computer. The cover of the device is designed with good cooling performance and 3D printing manufacturing method in mind. The properties of the designed laboratory power supply are verified by the final test measurements.
