Thermoelectric Power Generator

In this paper modeling and simulation of thermoelectric generator (TEG)modules is validated using MATLAB. The TEG model is developed with suitable mfiles and further the model is extended for generating electricity from waste heat liberated by air conditioners. These waste heat may lead to global warming and causes pollution. Hence this problem is addressed in this paper and thermoelectric generators are used to generate power. TEG is called a green technology as all parts are fixed and power produced is not wasted. Thermoelectric power generator converts waste heat in to electric energy. Hence thermoelectric power generation technique aids in the conversion of waste-heat energy into electrical power .So the economical wastage of thermal energy is avoided .The power production is abundant and also atmospheric pollution is avoided. As a result overall conversion efficiency of system is enhanced. The produced energy can be used for lighting a LED bulb, charging the mobile batteries.

The prototype of the electric smart stove is an electric stove with briquette fuel from teak leaf waste. The thermoelectric module used is 12 units of a Peltier TEC-12706. Thermoelectric generators take advantage of the Seebeck effect with temperature differences from both sides of the Peltier will produce electrical energy. The developing prototype method of an electric smart stove is carried out in 4 stages. First stage, analyzing geometry requirements and smart stove shape. Second stage is the process making of an electric smart stove. Third stage, installation of a power plant. The fourth stage, measurement of electrical power output. Based on the experiment, it is found that the thermoelectric generator produces 1.31 volts of electrical energy with a delta T of 40 degrees Celsius. As the result, an electric smart stove has not been able to charge the battery because the electric energy produced tends to be small.

This paper presents a calculation algorithm for a thermoelectric generator fitted in the exhaust system of a combustion engine. The viability of the presented calculation method was verified on an actual combustion engine. The calculations were performed for a BMW engine, and the generator design was based on a prototype from the same manufacturer. The paper includes calculations of the thermal cycle and of the parameters of exhaust gases from the engine. Subsequent calculations cover heat transfer from exhaust gases to the thermoelectric module and the amount of electric energy obtained from a series of modules.

With the natural sources of energy such as fossil fuels is slowly depleting, it became a trend to find new sources of unlimited energy. Renewable source of energy is the best source of unlimited energy for it will be utilizing the resources around like solar, hydro, wind, and many more. One of those newly developed renewable sources utilizes the waste heat developed by individual machines. Since electrical generating machines that use combustion engines generate a considerable amount of waste heat energy from the exhaust gases. Hence, this study focused on waste heat energy harvester by the use of the thermoelectric generator. Thermoelectric power generation is based on a phenomenon called the Seebeck effect. When a temperature difference is established between the hot and cold junctions of two dissimilar materials, a voltage is generated. The heat flow circulation through the semiconductors causes a displacement of charge carriers. A larger delta temperature creates a larger electrical current, ideally, but it is coupled with the fact that a semiconductor is effective only on a temperature range making the thermoelectric generators operational on a limited delta temperature. Primarily, the device was composed of a thermoelectric module mounted on an aluminum plate and placed in an oven. The main objective of the study is to design a circuitry for the thermoelectric generator that aimed to generate a minimum of 20 watts in order to power an AC load. In order to validate the device fabricated, certain measurements needed to be taken during the operation of the prototype. Thus, this device is now a developing source of alternative energy with further studies and innovations for commercial purposes.Keywords: thermoelectric generator, Seebeck effect, semiconductors*The paper has been selected from a collaboration with IPST and 7th ICFCHT 2019 for a conference entitled "Innovation in Polymer Science and Technology (IPST) 2019 in Conjunction with 7th International Conference on Fuel Cell and Hydrogen Technology (ICFCHT 2019) on October 16th - 19th at The Stones Hotel Legian, Bali, Indonesia"

The subject of the analysis was the optimisation of interoperation between the photovoltaic battery (PV) and DC motor, which drives a fan, with respect to the maximum efficiency of conversion of the electric energy into mechanical energy. Based on the block diagram, a mathematical model of this circuit was developed to ensure the mutual matching between the Maximum Power Point (MPP) of the battery and the receiver operation point. A computer simulation of the battery characteristics was conducted taking into account the changing MPP location on the characteristic vs. changes in solar radiation and temperature. The issue was considered for the optimal motor excitation coefficient, both changing and averaged in time. The energy conversion efficiency was determined for selected PV modules, as well as time.

Abstract. Besides the material property and dimensional optimization of the thermoelectric module, temperature distribution uniformity on the hot junction of the module surface highly affects the outputs of the thermoelectric power generation system. This paper reports the findings on the effects of non-uniform input temperature distribution on the performance of thermoelectric power generation system. To assure the investigation, heat transfer model and finite element formulation of thermoelectric module having non-linear material property have been developed. In addition to the experimental data from a real thermoelectric device, thermoelectric power generation system modeling and simulation using finite element packaging ANSYS software was carried out. For the simulation, temperature dependent thermoelectric material properties such as the Seebeck coefficient, thermal and electrical conductivity have been considered. The experimental and simulation results indicate that keeping the temperature distribution uniform on the hot junction of the thermoelectric module results higher efficiency, higher power, voltage and current outputs than the non-uniform temperature distribution.

Macromodels of transformers with different types of relationships (not only inductance but also capacitance) on the basis of circuits with quasi-distributed parameters simulation were proposed. The analysis of resonant modes and frequency characteristics of transformers on the basis of katkons with identical parameters at the open and closed secondary circuit were obtained. Results of the study will help to evaluate the effectiveness of the practical application of these transformers to improve power factor and efficiency of the transmission, distribution and conversion of electric energy. Using the correct transformers macromodels on the bases of katkons with strong and weak coupling makes possible to realize polyfunctional filter-compensative devices and current-limiting devices with reduced weight and dimensions.
