AC power supply with remote control
Štěpnička, Martin ; Papica, Petr (referee) ; Kubíček, Michal (advisor)
The project describes the design of controlled inverters or power generator simulating one phase of European or American distribution network. The generator is able to enter into an output signal of a certain fault conditions designed to testing the electromagnetic compatibility of connected devices. The text is divided into three main chapters. The first one deals with the design of the power generating low-frequency signal. The second part describes the power source used for this generator. In the third section describes the program management unit. End of text summarizes the results. The annex contains a schematic designs and printed circuit boards.

Low frequency active artificial load
Lízner, Václav ; Papica, Petr (referee) ; Kubíček, Michal (advisor)
This diploma thesis is focused on synthetic loads, especially electronically controlled loads. The thesis analyse principles of mechanically and electronically controlled loads and theirs operation modes. The paper also carried out a search of AC loads available on the market. The parameters of the AC load were based on the requirements provided by client. The functionality of the designed load is verified by simulation. The thesis continues with realization of the designed schematics and bringing the load to function. At the last section of the thesis are detail parameters of the designed load verified by measurement.

Class D audio power amplifier with microprocessor controlling
Nedbal, Jan ; Papica, Petr (referee) ; Brančík, Lubomír (advisor)
The thesis deals with the design and practical realization of class D audio power amplifier with microprocessor controlling. The first part describes the integrated circuits used in a preamplifier and his complete design with a description of the control program for ATmega128 microcontroller. The following part describes an integrated power amplifier TAS5613 and his circuits. The next section describes a switching power supply design using integrated circuit TOP261EN. The last section describes measurements of parameters of individual parts of the amplifier.

Design of switching stereo audio power amplifier
Konečný, Jiří ; Papica, Petr (referee) ; Brančík, Lubomír (advisor)
This text analyzes characteristics of audio power amplifiers in class D. The emphasis is placed on more detailed analysis of modulators, drivers, connection topology of power transistors. In the next section of text are analyzed available integrated circuits of power amplifiers in class D which are manufactured by world producers. The last part describes design of all parts of amplifier in class D with discrete components and also of power supplies. According to the plans, the individual parts are made. All parts are tested by measurements and results are evaluated.
