This paper presents considerations on the possibility to use thermoelectric generators at low temperatures to recover waste heat recovery applications, especially from geothermal energy. Thermoelectric generators have a satisfactory efficiency, when they are usually used in conditions with high gradient of temperatures. However, there are many applications, which lose important quantities of energy...
This work deals with the design and a prototype implementation of a maximum power point tracker (MPPT) for a thermoelectric (TE) module aiming to improve energy conversion efficiency in battery charging. This system uses TE devices that directly convert heat energy from a water gas heater to electricity to charge a battery. The TE module exhibits a non-linear I-V characteristic and its maximum power...
Geothermal and solar heat are attractive and environmentally clean energy sources for future power systems where solid state generators may become more important. In this paper, a generator model for such a novel conversion system is presented. Benefits and constraints are shown using a thermoelectric generator for solid state power conversion. For system efficiency improvement and power maximization,...
