Abstract: Thermoelectric power generation is a new kind of environment-friendly energy technology with reliable
performance which can transfer waste heat energy into electricity. The device of thermoelectric conversion based
on Seebeck effect is designed in this paper. Based on single chip processor and OP07 chip, the active I /V conversion
circuit is designed and the output voltage was displayed on the LCD1602. The output power from different temperature
differences is calculated and compared. The experimental result shows that the voltage generated from the
device increases linearly with the temperature difference,and the thermoelectric conversion efficiency of the device
is about 0.11%. The device can supply power to equipment with small power consumption.
Key words: Seebeck effect, thermoelectricity generation, thermoelectric conversion
