Class AB audio amplifier for two satellites and subwoofer
Cupák, Jan ; Brančík, Lubomír (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis deals with design of AB class audio amplifiers. Further more it deals also with other functional blocks, e.g. preamplifier, tone equalizer and active crossover. Outcome of this work is a complete solution of the amplifier with it's simulation. In final solution is also included scheme of a high quality power supply unit, speaker protection and heat sinks for high performance transistors. In this project is also included a solution of task about optimal mechanical arrangement of the single parts in the case of this amplifier. This thesis contains results of measurement and photo document of functional prototype.

Simulation and implementation of the audio power amplifier
Svadbík, Pavel ; Kratochvíl, Tomáš (referee) ; Šotner, Roman (advisor)
This work deals with simulation and analysis of audio power amplifiers of various concepts and classes. The theoretical part presents the basic necessary knowledge of electrical concepts and principles necessary for mastery of issues that this work deals. For each simulated circuit are described the basic operating principles and evaluated the results of the analysis. Based on the results of the analysis is chosen circuit, which is experimentally realized and measurement. In conclusion discusses the parameters obtained by simulations and practical measurements, and are fully assessed characteristics realized amplifier.

Class-AB stereo audio power amplifier
Chmelík, Šimon ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bachelor thesis deals with design of low-frequency power amplifier working in AB class, including correction preamplifier and a suitable power source. The amplifier is designed to be feasible from commonly available components. The result is the overall design of power amplifier with preamplifier and power supply and measuring their parameters.
