Řiditelný spínaný zdroj 0-1000 V / 100 W / Controllable switching power supply 0-1000 V / 100 W

Hofmann, Oldřich January 2017 (has links)
The thesis deals with the design and construction of a switching power supply with output voltage adjustable from 0 to 1200 V and rated power of 120 W, which will be used to replace the existing high voltage power supply for the irreversible electroporation (IRE) device developed at UVEE FEEC BUT. The thesis focuses on a basic description of the IRE device, a description of usable converter topologies and a selection of the best topology for the required purpose. The selection of the control circuit concept and its design are also integral parts of the thesis. The final part of the thesis contains the assembly of the power supply and the measurement verifying its function.

Spínaný stejnosměrný laboratorní zdroj 30V 60A / Laboratory DC power supply 30V 60A

Gábel, Marián January 2021 (has links)
The master thesis deals with design of a switched DC power supply with output parameters of 30 V 60 A. The power supply uses the connection of two single switch forward converters with opposite phase. The topology was chosen based on a comparison of specific schematics in the first part. The body of the thesis is covered in chapter which deals with design and analysis of power circuits of the converter. The chapter describes detailed design of pulse transformers, dimensioning of semiconductors and cooling system of the converter. For lower power losses, the system of synchronous rectifying is chosen at the output of the circuit. The regulation of the output is based on cascade structure with a superior voltage and dependent current loop. Appropriate over current protection is provided by sensing the output current and using current transformers for primary current measure.

Spínaný napájecí zdroj s planárním transformátorem / Switching Power Supply with Planar Transformer

Pawlas, Andrzej January 2010 (has links)
This master's thesis describes the development of switching power supply with planar transformer. Deals with selection of a suitable integrated circuit together with the topology, a purchase of prototype for the reference measurements and debugging its own power supply. Further design and implementation of planar transformer and in the final implementation, debugging, and measurment's its own prototype. Power supply was fully functional and reached the expected parameters.

Nabíječka lithiových akumulátorů / Li-ion accumulators charger

Vrba, Marek January 2012 (has links)
The main target of this thesis is to design and realize a prototype of a high capacity battery charger. The charger has been designed as a switching power supply based on a Flyback convertor with two transistors. As switching transistors the integrated circuit IR2110 has been selected. The convertor is controlled by a microcontroller board based on ATMega328 called Arduino Uno; some parts of the Arduino Uno Starter Kit are also used as LCD display, relay and button. In addition, an auxiliary source has been made; this one powers the integration circuit IR2110 and Arduino Uno board. Furthermore, this work introduces us to the processes of charging lithium batteries, types of lithium batteries and methods of charging the lithium iron phosphate (LiFePO4) battery.

Řízený laboratorní zdroj / Controled laboratory voltage suplier

Vít, Tomáš January 2016 (has links)
The aim of my master’s thesis is the design and implementation of laboratory power supply with output parameters 0-25V and 0-2A and options to manage this resource by elements of the front panel or via a computer control program. Content is the theoretical analysis of the possibility of subsequent theoretical sources suggesting that it verified on the prototype laboratory resources.
