Design of dual regulated power supply
Moštěk, Jiří ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor thesis deals with design and construction of a symmetric stabilized power supply provided with an adjustable electronic current fuse. The concept of source is chosen as a linear with two-output voltage ranges. The first range is possible to regulate the voltage from 0V to 20V with current limit 2mA – 4A or 2mA – 8A. The second voltage range allows you to adjust the output voltage from 0V to 40V with current limit 2mA – 4A. Included in this bachelor thesis is the simulation source, testing in non-soldering field, PCB design, commissioning, draft cooling and design of structural solutions. At the end of bachelor thesis are given the results of measurements laboratory resources and photos.

Converter for DC motor with sensorless speed control
Hanzl, Ondřej ; Martiš, Jan (referee) ; Tománek, Radek (advisor)
The scope of work is the design of a converter with sensorless speed control for a DC motor with permanent magnets with a power of 500 W at a voltage of 48 V. The whole device consists of two parts, a single-acting pass converter, which serves as a power supply with parameters 0 ÷ 60 V/0 ÷ 20 A for laboratory purposes, and on the hand as a power supply for a four-quadrant pulse converter for the speed control itself with user settings, electronic reversal of the direction of rotation and motor braking. The control of both inverters is provided by control circuits implemented digitally. All components will then be designed for measuring printed circuits boards of strandardized dimensions as plug-in modules to be built into instrument cabinet for easy disassembly and access in the case of controls.

Converter for DC motor with sensorless speed control
Hanzl, Ondřej ; Martiš, Jan (referee) ; Tománek, Radek (advisor)
The scope of the work is the design and implementation of a test sample of a converter with sensorless speed control for a DC motor with permanent magnets. The whole device consists of two main parts, namely a two-switch forvard converter, which serves both as a power source with parameters 0 ÷ 60V/0 ÷ 20A for laboratory purposes, and as a power supply for a four-quadrant pulse converter for the speed control of the electric motor. The control of both converters is ensured by digital control circuits. All components are placed on printed circuit boards of standardized dimensions as plug-in modules designed to be built into the instrument cabinet for easy disassembly and accessibility in case of checking measurements.
