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.

Laboratory Power Supply
Tománek, Radek
The paper is focused on a design of laboratory power supply with more outputs. During the design of the whole device reliability and EMC were the most important. The power supply was required to have many functions which common power supplies don’t allow. The article describes its basic characteristics, principles and unique voltage preregulators.

Digitally controlled linear power supply
Mikulka, Martin ; Šteffan, Pavel (referee) ; Háze, Jiří (advisor)
This bachelor thesis is focused on the design and realization of laboratory power supply with digital control. The power supply contains two separate galvanically isolated channels with output parameters in ranges of 0 - 24 V and 0 - 5 A. Output parameters are controllable independently via front panel or remote control. This power supply allows user to connect other channels meeting the condition of galvanic isolation and communication via the I2C interface. The content of this work is a theoretical analysis of the design of linear regulators, design with practical implementation and subsequent measurement.

Lab power supply 0-100 V / 0-100 mA
Hanzl, Ondřej ; Pazdera, Ivo (referee) ; Martiš, Jan (advisor)
The thesis deals with the design of a laboratory source of atypical parameters of the voltage range 0 – 100 V and current 0 – 100 mA, which will be used for testing LEDs, measuring the reverse voltage and characteristics of Zener diodes of unknown data. The power supply will operate in linear mode, where the output part make up a power unipolar transistor controlled by a controlled bipolar transistor. The control section controlling this output stage is a closed control loop with two PI controllers, a differential amplifier and a controlled limiter. In the control circuit, the controllers are arranged in a cascade structure, where the voltage regulator is superior to the current one. Power supply is provided by 2 transformers, one for the power part and the other for the control part. All designed and assembled components will be then placed in a box equipped with a digital measuring device with display.

Digitally controlled laboratory power supply
Spáčil, Petr ; Drexler, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the divison and research of DC voltage sources. It also describes how linear and switch mode power supply works. The 8-bit ATmega16 microcontroller from the ATMEL family of AVR microcontrollers is further described. Part of this bachelor thesis is the desing of the laboratory power supply source 30V / 3A, which is in the topology of switched pre-regulation. The ATmega 16 microcontroller provides measurement and displaying values on the display.
