摘要
A circuit which extends the operational life of a main power source, said circuit comprising a pair of thermoelectric generators (TEGs) for converting thermal energy from a heat source into electrical energy; a pair of capacitors arranged in parallel, each coupled to one of the TEGs for storing the electrical energy generated by said TEG; a power converter; a first switching element coupled between a first capacitor in the pair of capacitors and the power converter; a second switching element coupled between a second capacitor in the pair of capacitors and the power converter; and a monitor/controller coupled to said first and second switching elements and each of said capacitors for selectively and alternatively switching the first and second switching elements in order to selectively provide power from one of the capacitors to a load, thereby reducing the amount of power drawn from the main power source.
