  • Patent number: 8546680
    Abstract: An integrated micro-scale power converter converts hydrocarbon fuel into electricity. The integrated micro-scale power converter includes a micromachined combustor adapted to convert hydrocarbon fuel into thermal energy and a micromachined thermoelectric generator adapted to convert the thermal energy into electrical energy. The combustion reaction in the combustor flows in a path in a first plane while the thermal energy flows in a second plane in the generator the second plane being nearly orthogonal or orthogonal to the first plane. The fuel handler in the combustor is adjacent and thermally isolated from the thermoelectric generator. The fuel handler may include a nozzle and gas flow switch, where the frequency of activation of the gas flow switch controls the amount of the fuel ejected from the nozzle.
