3f. inverter with drive control for drill press
Grom, Martin ; Vašíček, Adam (referee) ; Procházka, Petr (advisor)
Bachelor thesis deals with the design and implementation of a three-phase converter designed for driving an electric drill with asynchronous motor. Converter is designed using a specialized integrated control circuit and transistor power module. The thesis also contains description of the induction motor control, description of the inverter internal operation, functions of integrated circuits, overall design description and design of the printed circuit board. The proposed device has been built and tested. The test measurements were done on a working sample of the converter.

Voltage doubler design in 0,25 m CMOS technology
Synek, Ladislav ; Prokop, Roman (referee) ; Radhoštěm, Milan Valenta, ON Semiconductor, Rožnov pod (advisor)
This diploma thesis deals with the design of a partially integrated charge pump in 0.25 micron technology ACMOS. The work is divided into two main parts, theoretical and practical. The theoretical section describes in detail various topologies of higher voltage generation of a charge pump and selected methods of regulating the output voltage of charge pumps. The practical part deals with the the actual design of a charge pump together with the arguments for the choice of the TPVD topology and the type of the regulation. Three regulation methods of a charge pump were implemented, tested and are dealt with: Pulse Skip, Constant frequency and PWM. There are 3 sub chapters, each describing a different regulation method, defining all the key elements of the design of such a charge pump and the results of the simulations are discussed. Conclusion of the thesis summarizes the results of the design of charge pumps, comparing them on the basis of the chosen type of output voltage regulation.

Tutorial kits for course Powering electronic devices
Pochobradský, Jakub ; Švábeník, Petr (referee) ; Kubíček, Michal (advisor)
The goal of this bachelor thesis is to make a design of tutorial kits with a charge pump, DC/DC converter and a reference voltage and current sources that could be used in laboratory classes. In the first part basic principles of a charge pump and DC/DC converter are described. The second part is related to integrated circuits that are specific for construction of charge pumps and DC/DC convertors. The third part contains design of printed circuits.
