Abstract
The invention relates to an arrangement comprising a thermo-electric generator having a hot side which absorbs heat from a heat source, a cold side which discharges heat to a heat sink, and electrical terminals for outputting electrical energy with an output voltage and an electric circuit with a maximum permissible input voltage, the inputs of which are connected to the electrical terminals of the thermo-electric generator. Such arrangements may be used, for example, in exhaust systems of motor vehicles for more efficient use of the energy. In order to provide such an arrangement, which can be connected to a heat source, in particular an exhaust system of an internal combustion engine, largely independently of the magnitude of the temperature difference between the hot and cold sides of the thermo-electric generator, it is proposed that the thermo-electric generator be configured in such a way that saturation of the output voltage occurs below the maximum permissible input voltage of the electric circuit, or when said maximum permissible input voltage is reached.
