5kV 40uA from 120VAC

Kooner · 2011-07-07T20:12:23+00:00

Can someone suggest a topology for converting a 120VAC input to a5kVDC output at 40uA? The line and load are fixed so the supply doesnot have to be regulated. Low parts count is a plus.I looked at the Bandaxall circuit posts and ran a few simulations. Itlooks like the input voltage is limited to the Vgs breakdown. Therectified 120VAC is approx 170VDC which is too high for the Bandaxallcircuit...right??Jason Kooner

Looks like it worked... on both of you.

Bwuahahahahaha!

OK, then tell us what the opamp is for.

And calculate the efficiency at 2 uA load.
