Microcontroller Based Thermoelectric Generator Application

Abstract

In this study, a microcontroller controlled thermoelectric generator which transforms geothermal energy, one of the renewable energy sources, to directly electrical energy was designed, and then the system was tested and its performance analysis was examined. In the system, energy transformation is provided via the Seebeck effect in the thermoelectric modules. Since changeable DC voltage depending on temperature difference is obtained by the thermoelectric modules, the accumulator, regulator circuit and DC/AC convertor are used in order to obtain the values 5V DC, 12V DC and 220V AC in the electrical energy. System control signals are arranged by using the PIC16F877 microcontroller in the system. The system is quite useful to meet electrical energy needs easily, cleanly and cheaply from the geothermal sources.
