Abstract
A thermoelectric generator includes a voltage source including a thermoelectric element, a starting circuit connected to the voltage source, a DC to DC converter circuit connected to the voltage source, an output connected to the starting circuit and connected to the DC to DC converter circuit, and a controller having an input connected to the voltage source, and outputs connected to the starting circuit and to the DC to DC converter circuit. The controller deactivates the starting circuit and activates the DC to DC converter circuit when a voltage at the output or when a voltage provided by the voltage source rises above a predefined upper voltage threshold. Additionally, the controller reactivates the starting circuit and deactivates the DC to DC converter circuit when a voltage at the output or when a voltage provided by the voltage source drops below a predefined lower voltage threshold.
