Usage of High Power Inverters in High Voltage Sources
Zemánek, Miroslav ; Janča, Jan (referee) ; Boušek, Jaroslav (referee) ; Patočka, Miroslav (advisor)
This work is concerned with power inverters for alternate high voltage power sources. The theoretical part describes the topology of inverters that can be used in alternate power sources. A model of voltage transformer is described in details to better understand the parasitic effects that are inevitably present in high voltage power sources and, therefore, have to be taken into consideration at the design of high voltage power sources. The work is oriented to problems of alternate high voltage power sources for ozone generators. This is the reason, why the theoretical and, partially, also the experimental part deal with the properties of ozone and its use. The experimental part solves high voltage inverter with capacitive load that is formed by discharge element of an ozone generator. Designed inverter is able to feed the capacitive load with high voltage at very short periods of time from several microseconds up to tens of nanoseconds. In comparison with the length of voltage pulses in common ozone generators, this pulses are more than 100-time shorter. This has a positive effect to silent discharge characteristics.

Sports Centre
Janča, Jan ; Havířová, Zdeňka (referee) ; Lavický, Miloš (advisor)
This Diploma thesis „Sports centre“ was made as a documentation for a building construction. The object of the sports centre is designed for 337 people and consists of two above-ground floors sports hall itself and joined one above-ground floor restaurant. It is detached building. Building is designed in slightly sloping terrain. The sports centre is located on the outskirts of city named Odry, within walking distance of residential buildings. The sports hall is divided into sections for athletes and referees, part for employees and parts for the public. The restaurant has own entrance from the western side of the building and is functionally connected to sports hall. The restaurant is further divided into units for the public and for the staff. The construction system of the sports hall is made of a prefabricated skeletal system based on baseplaces and a filling wall on the strip foundations, the restaurant is only bricked and based on the base on the strip foundations.

Timber Housing Building
Janča, Jan ; Hlásková, Michaela (referee) ; Lavický, Miloš (advisor)
The Bachelor´s thesis project documentation of detached timber house. House with two floors is L-shaped with adjacent one floor garage which is operationally connected to house. Above house is situated unutilized roof space which is consists of purlin roof. Garage is covered with flat roof. Whole house is not with basement. Total protortions of a house is 23x13 m.

Chytrá zásuvka s podporou měření proudů
Janča, Jan
This work is aimed at creating a prototype of a smart socket that is able to measure the current power consumption and remotely switch on an individual socket. The prototype itself is built on an Arduino microcontroller and Arduino compatible components. Subsequently, all components are placed in a 3D printed box. The box is made of self-extinguishing material. A web interface is created for controlling the box, in which the current electricity consumption is found. This data is also stored on an SD card in a text file for future reference. The program for the Arduino is written in C++ and for the web interface using HTML.
