Abstract:
In this paper, a thermoelectric energy harvesting circuit that starts up at very low input voltages and harvests the very little energy of a variable temperature gradient is presented. It is based on a commercially available step-up converter Integrated Circuit (IC), with an adopted wiring scheme and some additional components to guarantee a stable operation for a sensor unit over a certain time. As a result, it turns out that load matching is suboptimal for the start up of the Thermo-Electric Generator (TEG) system in the case of small temperature gradients.
