  • Publication number: 20140208773
    Abstract: An improved circular multi-element semiconductor thermoelectric hybrid utilizes a make-before-break high frequency switching output component to provide nominal alternating current voltage outputs. Overall efficiency of heat conversion is improved by coupling a chiller to the thermoelectric generator where exhaust heat produces chilled liquid or air that is conveyed to the cold side of the thermoelectric device. The thermoelectric generator is used in a variety of transportation vehicles including manufactured vehicles, retrofitted vehicles and vehicle power combinations.

  • Publication number: 20140196274
    Abstract: A means for determining the electrical resistance and resistivity of thermoelectric material allows quality control at all steps in the construction of a bismuth telluride and antimony telluride thermoelectric generator. The method involves measuring negative thermoelectric voltage with no current flowing and then a measure of negative thermoelectric voltage while forcing known current through the material in the same direction as shorted to accurately determine thermoelectric resistance. A manual and automatic method of manufacturing thermoelectric rings using forcing current for in-process testing means.

  • Patent number: 8101846
    Abstract: High efficiency conversion of heat energy to electrical energy is achieved using a ring of metallic components and anodically sliced, reduced barriers, high purity n-type and p-type semiconductor wafers. Energy produced by heating one set of fins and cooling another set is extracted from a ring of bismuth telluride based n-type wafers and antimony telluride based p-type wafers using make-before-break control of MOSfet switch banks. Standard AC frequencies and DC output result from rectification of make-before-break high frequency switched very high currents in the ring and a DC to AC converter. Solar energy stored in porcelain fragments extends the time that solar energy can be used as the heat source for the thermoelectric generator device.

  • Publication number: 20100288322
    Abstract: Conversion of solar heat into electrical energy is achieved using a parabolic reflector, a heat transfer medium, a high-density heat store and a thermoelectric generator. The system is useful for various forms of stationary and moving applications. Using stored heat derived from sunlight provides day and night electrical supply over many days depending on the size of the solar collector and heat store. Moving applications are achieved using a mobile heat store with attached thermoelectric generator.

  • Publication number: 20090229650
    Abstract: A solid-state thermoelectric generator device can directly drive a high voltage grid at voltage without a special step-up transformer. Phase sensing, output voltage and waveform of the generator can be electronically adjusted to match parameters sensed directly from the grid, generator output adjusted to conform exactly to the grid. Three solar powered generators connected as a “y” with three legs with common earth grounds can power individual phases of the grid as a mini-power plant providing three-phase grid voltage electricity. Power quality correction to the grid can be made to individual phases of the grid on an automatic, self-correcting basis as needed.
