Cheers for the replies!
Sorry for the lack of details, but the TEG can generate 0.21 watt at a load of 100ohms and a temp difference of 27 degrees C. (57 hot side, 30 cold side).
Ye are right, unfortunately this wasn’t as much power as I was expecting. But its just an idea im trying to play around with. Its not ment to be perpetual motion theme (??), im just hoping to convert any waste heat into usable, albeit small, power. I have heard since that Thermoelectrics are only a few % efficient in generation mode.
As monkeyman said, I was hoping it would be self controlled.
Cheers for the post oznog, it was very helpful. I was thinking that since it’s a semiconductor device, the thermal conductivity of it would be good enough not to cause too much of a temperature difference, but a high enough voltage to be usable. As far as I can tell, the current output is proportional to heat flux through the device, so hopefully power output should be high-ish even if the voltage is low.
Does anybody know if the load is high on the TEG that the heat flux through the TEG will be reduced? And optikon, how did you build your 1v boost circuit?
