  • Patent number: 10658164
    Abstract: There is a need to produce electric power by means that provide low pollution and high efficiency. Thermionic energy conversion (TEC) systems enable the direct conversion of energy from thermal to electric, based on the emission of electrons from a heated cathode, Diamond is an ideal material for the cathode because of its high temperature mechanical stability, its ability to be created with low resistivity, and its strong tendency to emit electrons. The efficiency of current TEC systems is not practical, as above approximately 700° C. the current produced decreases. The presence of hydrogen at the electron-emitting surface is required to enhance thermionic emission. The present invention provides a resupply of hydrogen to the emitting surface by diffusion of hydrogen through the diamond cathode, and enables efficient operation of TEC systems at temperatures well above the current limit; practical systems for direct conversion of heat to electricity are thus enabled.

  • Patent number: 10536072
    Abstract: A circuit includes a transformer configured with a primary winding and a secondary winding that are driven from a voltage supplied by a thermoelectric generator (TEG). The circuit includes a bipolar startup stage (BSS) coupled to the transformer to generate an intermediate voltage. The BSS includes a first transistor device coupled in series with the primary winding of the transformer to form an oscillator circuit with an inductance of the secondary winding when the voltage supplied by the TEG is positive. A second transistor device coupled to the secondary winding of the transformer enables the oscillator circuit to oscillate when the voltage supplied by the TEG is negative. After startup, a flyback converter stage can be enabled from the intermediate voltage to generate a boosted regulated output voltage.
