Current and/or voltage controlling device for thermoelectric generator for electrical system of car, has voltage divider circuit with semiconductor component whose conductivity is influenced by output voltage of thermoelectric generator

摘要

The device has a voltage divider circuit (ES) arranged between a thermoelectric generator (TEG) and an electrical load (L). The voltage divider circuit includes a semiconductor component whose conductivity is influenced by an output voltage of the TEG such that increase of a current value in a given operating point reduces a voltage of the TEG. The voltage divider circuit includes an NPN transistor (T1), a MOSFET, a resistor (RB1), and a zener diode. An independent claim is also included for a method for controlling a current and/or a voltage of a TEM.
