The objective of this paper is to utilize the waste heat energy being generated in automobiles. It involves the trapping of heat energy being generated from the vehicles, such as silencers in bikes and converts the waste heat to electrical energy which can be used for many appliances. Thermoelectric Generator (TEG) which works on Seebeck effect. In this paper, SEPIC is designed and implemented to overcome this problem. The electric potential produced in thermoelectric generator is boosted by the SEPIC thereby increasing or decreasing the magnitude of voltage, required for charging battery without reversing the polarity of the supply. The waste heat can be utilized efficiently, which will be clean and green and can also be applied for both the industrial purposes and domestic purposes. The improved performance parameters are constant voltage and current, efficiency is high and low ripple with desired output voltage.
