	I'm no a magnetics designer but that sounds like a HUGE device to me!
If the charging frequency was 120 Hz the reactance of the 5 henry choke
would be about 3770 ohms and the voltage across it at 1 amp would then
be 3770 volts.  If it is to pass 1 amp the wire size would probably have
to be around #22 even for intermittent operation, and the resulting wire
area would require a large core.  Real designers step forward?
