dc power boost
(OP)
I have a dc source of about 1 volt and I am looking for a circuit to boost the voltage to 2 volts at 20 ma

These are just some thoughts, I hope they help
RE: dc power boost
I'm not sure how low these circuits can go (PS voltage) but I think that some might be able to run as low as slightly less than 1 volt.
Where does the 1 volt come from? It's an odd voltage.

RE: dc power boost
much lower input V, using synchronous vibrator ...

RE: dc power boost
electromech. vibrator chops lowV for xformer. extra two
-- SPDT-- contacts ground one end of secondary. The centertap is the DC output.
I suggest a better solution:
Use 3-4V rechargable battery to drive oscillator-FET swith.
FET chopps low V; start from battery, recharge it from AC output.

The thermocouple was a pilot flame detector salvaged from an old gas hot water heater. The thermocouple generated around 10mV at 50mA (from memory) when attached to a soldering iron tip !
I did get my six volts, but even my multimeter loaded the output significantly. Flea power indeed, only half a milliwatt input power, but it was an interesting thing to try.
It is what happens during retirement, too much spare time.

Sweet.
Thanks for that info nbucska!
Warpspeed.. external powered... uh huh.. with that sneaky balancing resistor in there between the external power and the thermopile??
Yeah I bet it had horrible load regulation. Flea complain?

Westinghouse made the power supplies I saw. It was the same division that built sonars and polaris submarine systems. I don't think it exist anymore.

As you might imagine, since TOW dates back to Vietnam and any other form of energy storage would bleed down over any normal military storage, a more permanent energy source was needed. The thermal batteries, once the chemical stability is dealt with, can be stored for long periods, and then removed and immediately used.
