OLTC-Inductors



Original poster: "Terry Fritz" <twftesla-at-qwest-dot-net>

Hi All,

I have been working on the inductors for the OLTC tonight.  Actually, just
thinking about them...  The "specs" are:

1.  Easy to make and reproducible by your average coiler (or easy to just
buy out right).

2.  Light weight since this coil is "hoot'n and toot'n" about no heavy "big
iron" stuff in it.

3.  Can reasonably handle the voltages and currents shown (note that the
current is 100X in the pic):

About 5.5 amps peak and 650 volts peak.

3.  The FT looks like this:

Looks like all 100Hz to 1kz stuff.

4.  There are two inductors at 75mH each.  They could probably be on the
same core in some common mode if that would make things easier.

Here is the system schematic (Lb1, Lb2):

5.  Not too expensive, but realizing this is probably like a $500 class coil...

If anyone has any ideas here they are very welcome :-))  Either on list or
direct to:

I guess it could be one 150mH inductor, but the filtering and "balance"
seems more natural with two inductors.

Cheers,
