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.

Design and construction of audio power amplifier
Růžička, Jaroslav ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
This bachelor’s thesis is concerned with amplifier classes, integration end-level, protective circuits and concrete concept of class AB power amplifier, including concept of preamplifier and power amplifier. Features of designed circuits were simulated in PSpice software. These individual concepts of modules are connected with DPS. This thesis contains results of measurement and photos of amplifier.

Design and making of low-frequency power amplifier in class AB
Dušek, Martin ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
In this bachelor thesis I am occupied with low frequency amplifiers, theirs important parameters, classes and with integrations end-level. Next I am occupied with miscellaneous types of preamplifiers and additional circuits. There are simulated schemes of corrective preamplifier, protections scheme and high power amplifier in PSpice software in this thesis. These schemes and next additional modules are connected with DPS. This thesis contains result of measurement and photo functional sample.

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.
