Class AB stereo audio amplifier with output power 2 x 120 W / 4 ohms
 Pavlovič, Matúš ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
In this bachelor thesis we will deal with the design of a stereo amplifier with a power stage in working class AB with a nominal power of 2x120 W / 4. We decided to design the audio amplifier itself into blocks, while we can expand the individual blocks by others if necessary. In the first chapter we propose frequency corrections for an audio amplifier using operational amplifiers. In the second chapter we will propose an indication of the excitation of the audio amplifier, using the integrated circuit LM3915 in connection with LED diodes. In the third chapter we will design the power stage of the audio amplifier operating in class AB with a power of 120 W. In the fourth chapter we will design the protection of the connected speaker to the amplifier. In the sixth chapter we will design the power circuits for the audio amplifier. The next chapters will describe the implementation and measurement of the proposed audio amplifier.
