For schematic of my "controller" see http://www.oil4lessllc.org/Misc/ .
Some responders in the past indicated that the source had to be
pulled down to ground for the dratted IR2118 to work properly.
Note in my case i need the output to be adjustable from somewhere
near ground (50V will do) to somewhere near supply (120V), and that
voltage have little ripple (say under 10% or 10V - whichever is
reasonable for supply to bottom of flyback in TV.
As shown, i do not get an adjustable voltage, and it is fairly low.
Clues please to get this to work (or an alternate that is cheeep.
Thanks.
