Simulation and realization of laboratory DC power supply
Mach, Ladislav ; Koton, Jaroslav (referee) ; Šotner, Roman (advisor)
The thesis deals with analyses of the laboratory symmetrical supplies with adjustable output voltage. It also describes different kinds of current cut-out circuits and several most frequent supply connection schemes. Analyses (simulation program OrCAD) show the characteristics and behaviour of the mentioned supplies. To set the output voltage, operational amplifier structures or linear three-terminal voltage regulator are very often used. The suggested supply was tested and its parameters compared with the simulations. The value of output voltage and current can be controlled with a computer with a USB port. For controlling of the output voltage and current the digital potentiometers were used and controlled by I2C bus.

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.
