Key Words: Thermoelectric Generator (TEG),Voltage Regulator, Thermoelectric Module. 1.INTRODUCTION Thermoelectric generator it is device which is use for the directly conversion of heat energy into the form of electrical energy. It is works on the seebeck principle Waste heat in manufacturing is generated from several industrial systems distributed throughout a plant. The largest sources of waste heat for most industries are exhaust and flue gases and heated air from heating systems such as high-temperature gases from burners in process heating; lower temperature gases from heat treating furnaces, dryers, and heaters; and heat from heat exchangers, cooling liquids, and gases. While waste heat in the form of exhaust gases is readily recognized, waste heat can also be found within liquids and solids. Waste heat within liquids includes cooling water, heated wash water, and blow-down water. Solids can be hot products that are discharged after processing or after reactions are complete, or they can be hot by-products from processes or combustion of solid materials. Other less apparent waste heat sources include hot surfaces, steam leaks, and boiler blow-down water. Exhibit 1 shows typical major waste heat sources along with the temperature range and characteristics of the source. 1.1 THERMOELECTRIC GENERATOR COMPONENTS Thermoelectric power generator basically consist of four major components :  Hot side heat exchanger  Themoelectric module  Cold –side heat exchanger  Copper electrodes 1.2 CONVENTIONAL MATERIALS There are many TEG materials that are employed in commercial applications today. These materials can be divided into three groups based on the temperature range of operation: 1. Low temperature materials (up to around 450K): Alloys based on Bismuth (Bi) in
