Abstract

This bachelor thesis deals with the possibilities, how to gain energy out of the surrounding for powering the embedded system with low-power consumption. As the source of power, thermal energy is used. In the thesis, there are listed the basic possibilities how to gain, convert and store the electrical energy. The thesis is mainly focused on the construction of the measuring device, which serves as a means for determining the potential amount of energy generated by Peltier cells. The thesis also contains the design and realization of the measuring chain, used for the recording of the measurement data with the use of the virtual instrumentation and measuring card. This data provides the basic overview and characteristics of the measured thermoelectrical converter. For the need of transformation and powering, there was chosen the suitable DC-DC converter with the ability to store the energy into the Supercapacitor. Afterward, the DC-DC converter was connected for the supposed usage with the low-temperature differential according to the discovered assumption of the gained energy. Its parameters are further verified by the measuring which is realized utilizing the laboratory power supply and measured Peltier cell.
