摘要

The aim of this paper is to develop an experimental study on the effect of the magnetic field on thermoelectric generators (TEG) that have been used in the past until today according to the Peltier-Seebeck(PS) effect as a bidirectional conversion system of heat and electrical energy. The magnetic field is generated by using a common stator-field(SF) having two pole-shoes expansions shaped in a cylindrical symmetry both winded by two coils connected in series and powered by ac-source. The experimental set-up is performed by using customized jigs manufactured by a 3D printer in order to locate capacitors that allow to carry out magnetic field value coming from the stator field. The magnetic field has been calculated then by using Maxwell's equations in order to identify the induced voltage on the pn-joints characterizing the TEGs. The calculation of eddy current induced in the pn-joints plays a key role in developing the expression of the voltage coming out of the electrical wires of the TEG tile. The theoretical expression of voltage has been validated experimentally by tuning the integration parameter carried out in the current density expressions. The validation is successful but the most important thing is the usage of TEG tile in an environment where there is a presence of a magnetic field in order to carry out a voltage which has never been done before.
