ABSTRACT:
A resonant thermoelectric generator includes a thermoelectric power converter connected in series with a resonant circuit. A current generated by the thermoelectric power converter is cycled back and forth in the resonant circuit. The polarity of the thermoelectric power converter with respect to the resonant circuit is switched back and forth to correspond with the direction of the current. In a second embodiment, the thermoelectric power converter is coupled to the resonant circuit through a transformer, and its polarity is also switched to correspond with the direction of the current. In both embodiments, a negative retarding voltage that builds up in the thermoelectric power converter is eliminated by switching its polarity to always correspond with the direction of the current, so that energy is added to the resonant circuit in each cycle, and power is very efficiently converted from heat directly into electricity.
