Design of a kit for the creation of a supply point for electricity generated from renewable sources
Fridrich, Jiří ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This project deals with the design and realisation of a set that will work as a power supply point with electricity generated from renewable energy sources. The theoretical part deals with information about renewable energy sources and energy storage options. In the practical part, a mobile kit for powering variable message traffic signs is designed. It uses photovoltaic panels and stores energy in a lead-acid battery. A methanol fuel cell is used for backup power. The device is adapted for use in road traffic and meets the requirements of the relevant authorities. To verify the stability of the structure, there were performed static calculations, which proved the ability of the device to withstand wind stress. Part of the work was to draw a complete production documentation, which was used to create a test sample. Long-term measurements of energy flows in the system were performed on that sample. These measurements confirmed the ability of the device to operate autonomously and the possibility of using it for the required purpose.
DC to DC inverter for backup power supplies with super-capacitors
Fridrich, Jiří ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
In this project is described a design realisation of DC/DC converter using supercapacitors, input voltage 36 V from power supply, which is converted to 5.6 V and stored to the supercapacitors and then converted back up to 36 V. This convertor is controlled by Atmel.
