Uninterruptible Power Supply
Mrázek, Petr ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
The thesis deals with Uninterruptible Power Supply (UPS) and associated problems of backup power in case of unexpected outages of electricity. Start of work is dedicated to limitation of the electricity supplies, as well as their causes and consequences. Furthermore, brief history of UPS and subsequently distinguish between UPS’s architectures. There is also a description of the energy sources such as batteries, flywheels or fuel cells. Part of thesis describes security of electricity supply in health care facilities, including requirements for emergency power. The own design of UPS is described in the end.

Mechanical Design of Flywheel Energy Storage System
Hanáček, Jiří ; Šebesta, Karel (referee) ; Hartl, Martin (advisor)
This bachelor thesis focus on flywheel energy storage construction. The aim of the work is to discuss nowadays construction types of each component of these batteries. Single chapters are focused on rotor, bearings, motor generator and enclosure of the system. There is shown a basic principle of each component and itsfunction within the battery system, used materials and shapes and other factors influencing the construction. This thesis is also focused on stress analysis of metal and composite rotor, rotor fit with help of magnetic bearings, power transfer with help of motor generator and on the enclosure design of that mechanical battery.

Transmissions of Passenger Cars with Hybrid Drive
Vaňourek, Jakub ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This thesis deals with transmission systems of passenger cars with a hybrid drive. The main reason for choosing this topic was its topicality. With increasingly strict emission standards, hybrid cars are coming to the fore. The first part of the thesis deals with the division of hybrid drives into individual categories according to the selected criteria. An example of a specific solution is then given for the individual categories and its construction, functionality and its advantages and disadvantages compared to cars with an internal combustion engine are described. In the following chapters, more complex hybrid systems are described in more detail in connection with construction and functionality. The conclusion is dedicated to evaluating the mentioned hybrid systems and outlining their potential use in the future.
