Re: cheap 200A AC to DC power supply?

If you can insulate the Peltier elements, it would generally be easier
to provide 170VDC at 17A. If the insulation is REALLY good, you could
just rectify and filter the 120VAC, or preferably work up a PFC front
end to provide both regulation and an input current waveform that
doesn't trip out every breaker you connect it to .... or else rethink
the project or the budget.

I want to power 10 thermoelectric heat pumps at once from wall power.
(120VAC 60Hz). Ripple is somewhat important for these, but precise
voltage and current regulation is not. Each heat pump draws 17A at full
power, plus I need some extra current for fans, pumps, etc.. The heat
pumps need about 17V at full power. So I need an AC to DC power supply
which takes 120VAC 60Hz and outputs 17V at up to 200A. Could someone
point me in the right direction here? It needs to cost less than $200.
Ripple hurts these heat pumps but if its very slow I dont think it will
matter, even if its a couple volts. Current can vary up to say an amp.
