Abstract
An energy boost circuit adapted to provide power to a load is described. The circuit includes a pair of thermoelectric generators (TEGs) for converting thermal energy from a heat source into electrical energy; a pair of capacitor banks arranged in parallel, each coupled to one of the TEGs for storing the electrical energy generated by the TEG; a power converter; a first switching element coupled between a first capacitor bank in the pair of capacitor banks and the power converter; a second switching element coupled between a second capacitor bank in the pair of capacitor banks and the power converter; and a monitor/controller coupled to the first and second switching elements and adapted to selectively switch the switching elements in order to provide a power boost to the load, where the monitor/controller automatically switches the switching elements based at least partly on charge levels measured at the capacitor banks.
