Thermoelectric generators（TEGs） directly convert heat energy into electricity for power-supplying sensors and other portable electronic *** this paper,a maximum power point tracking（MppT） controller in the modifiedperturb and observe（p＆o） algorithm was designed on the basis of analyzing the output characteristics of the TEG *** MppT controller consists of a voltage sensor,a current sensor,a microcontroller and a SEpIC converter,which keeps the operating point of the thermoelectric generator tracking the maximum power point（Mpp）.The thermoelectric generator was heated to generate electricity,and a supercapacitor accumulated that *** results using the MppT controller present that the thermoelectric generator’s output voltage achieves around 5V,the output power achieves upward of 2W when the temperature difference △T=75℃,and the operating point of the thermoelectric generator accurately tracks the Mpp with a tracking efficiency of 99.8%;the charging power can be improved 89.65%.
