Power supply and protection circuits for 6-channel audio amplifier
Kryška, Vojtěch ; Balík, Miroslav (referee) ; Hanák, Pavel (advisor)
This bachelor thesis deals with designing protection circuits for 6 channel audio amplifier. Created circuits provide AC voltage filtering, current peak limitation after switching on, delayed speakers connection for eliminating crackling, automatic shut down in case of overheath, LED indication of failure and waking up from standby mode. Created design focuses on keeping all channels grounds unconnected with each other for eliminating ground loops.

Audio power amplifier 2 x 500 W
Petrgál, Filip ; Brančík, Lubomír (referee) ; Hruboš, Zdeněk (advisor)
This bachelor’s thesis deals with low frequency power amplifier, distribution, and involvement of important parameters. Furthermore, the second deals with the preamplifiers, power supplies, amplifier circuits protections and other additional modules. Elaboration includes simulated proposals to address preamp, power amplifier output stage as well as protection circuitin PSpice program. Proposes that these modules is shown in the detailed diagramdescribing the components.

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.

Temperature measurements with PT100 for aerospace applications
Závorka, Radek ; Dobesch, Aleš (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with design of temperature measurement system, which is focused on aviation applications. The design emphasizes fulfilment of aviation standards, especially protection against voltage needle pulses and transient phenomena caused by lightning. Device must be resistant against electromagnetic interference. The core of equipment is AD converter with current source from Texas Instruments, which is suitable for connect different type of sensors. The whole system is controlled by microcontroller from ARM series. The measurement values are display on monitor of computer, which is connect by serial line.
