Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.

Audio power amplifier 2 x 50 W
Skalický, Pavel ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
The topic of my bachelor´s theis is design of class AB audio power amplifier 2 x 50 W/4 with preamplifier and stereo output. The design is standard solution of stereophonic version of power amplifier, with monolithic integrated circuit 2 x LM 3886. The project deals also with preamplifier with integrated circuit LM 1036, calculation of heat sink of power circuits and solution of supply. The aim of this bachelor´s project was make complete design of laboratory prototype (scheme, layout of printed circuit, part list and placemnet, amplifier arrangement), realisation function of prototype and laboratory measurements.

Flexible generators of electrical energy
Tesařová, Tereza ; Holcman, Vladimír (referee) ; Tofel, Pavel (advisor)
This bachelor thesis is focused on actual research part of energy harvesting technologies – flexible electrical generators, which mean the special generating of electricity using specific flexible materials. The net charge result is affected by the incidental mechanism to transform certain energy form into electrical power and is influenced of material range, which determines what will be harnessed as a source of energy. The energy harvesting is aiming at producing alternative and efficient ways instead of harmful and strained manufacture processing.
