DC Supply
Greg L. wrote just recently commenting on the 'lack-of' viability of DC-HT
supply for coiling using single-phase supplies.
No argument, just a few comments / questions.
Presumably, with 3-phase supplies DC is OK as you can "fill-in" the valleys
which would otherwise render useless many presentations of the RSG.
Understand & accept async-RSG better than sync-RSG, as allows wide range of
BPS and hunting for the optimal F(bang) for a given system.
I am not EE based, but seem to remember it is possible to retard the phase
angle of a mains supply. Is this true ? (or am I really losing my mind
as the wife thinks)
IF SO .......
Why not use a number of NSTs at different phase angle. Rectify each for a
somewhat lumpy DC-HT supply. Then try with async-RSG.
If tried. Would the diode-tubes help protect NSTs from return spikes ?
_________________________
Let me take this further. I am currently building a larger coil, which
would appreciate more bang than my current supply, but I'm not keen (threat
of divorce) on getting a PP.
Have genuine 3-phase to my house to supply a large air-conditioner. Could
use this, but will need a friendly electrician to supply parallel outlets
with same. IF I could phase shift AC supply to 3 NSTs (propose 10 kV / 120
mA each) then rectify this, seems this would be a good solution.
Comments welcomed.
