Class D audio power amplifier for bass guitar
Appel, Daniel ; Petržela, Jiří (referee) ; Brančík, Lubomír (advisor)
The main goal of this project was a synthesis of audio power amplifier and preamplifier for bass guitar with features suitable for this kind of instrument. The project was divided into 6 parts. The first part is a brief introduction to classes of power amplifiers, the second part is about function of blocks of which the class d audio power amplifier consist. In the third part the designed circuits and their properties are discussed. The simulation of circuits in PSICE are also included in this part. The design of power supply unit is discussed in fourth part. In the fifth there is design of chassis and other mechanical constructions. In the sixth part, there are results of experimental measurements of the amplifier prototype. In the appendix of this bachelor thesis are enclosed the schematics, printed circuit board designs, and photographic documentation of amplifier prototype.

Optimization of Switching Regulated DC-DC Converter Design
Appel, Daniel
The goal of this project was an optimization of existing DC-DC converter design with regards to its efficiency, minimalizing power loses and radiated electromagnetic inference. Design and optimization of converter circuit, PCB, components and also measurement automatization in Simple are discussed in this paper.

Optimization of switching regulated DC-DC converter design
Appel, Daniel ; Ing. Jan Bartoň, Meatest, s.r.o (referee) ; Hejátková, Edita (advisor)
The main goal of this project was an optimization of DC-DC converter design from company Meatest with regards to its efficiency, minimalizing power loses and radiated electromagnetic inference, while maintaining its price on reasonable level. The first part of this paper is introduction to the most common converter topologies. In the second part, design and optimization of converter are discussed. The third part is about measurement automatization in Simple. Measurements of converter prototype can be found in fourth part.
