Abstract : A constant load line approach to electronically control the amount of liquid fuel supplied to the combustion system of a thermoelectric power source is presented. It is shown that, by sensing the output current of the thermopile converter and using this signal to control the speed of an electrically driven fuel pump, system sensitivity to variations in fuel properties could be eliminated and constant electrical output at the terminals of the thermopile assured. Circuit description of a sensor/evaluator concept and test data showing circuit performance when it is integrated in a 500 watt thermoelectric power source are presented. The appendix shows an analysis of the effects of heat flow and current flow and current flow on the thermocouple hot junction temperature, including the definition of fundamental thermal effects concerning thermoelectric power source theory.
