>>e started thinking Trace was purchased by some shady entity for the sole purpose of buying the rights of that device and crushing it. Thoughts of dark conspiracies, trench coats, hit men, lobbyists, and lawyers came to mind.

Your are very close here... That micro grid tie unit was...

I wish I could edit posts... I should also have said that in an inverter you do NOT want to operate very far into saturation, but it should be...

boB - Good luck putting your theory to test in practice.
I have many times, and I'm sure you have too. I think that there is just a definition problem here of the word saturation. I'm merely trying to state that there is a point on the B-H curve...

Another way to operate more in the saturation region .
You cannot operate more in the saturation region for all the reasons already mentioned above by jghrist, itsmoked and slavag.

Sure you can. Saturation is not just a "Yes or No" thing with soft magnetics... The B-H curve slope...
Another way to operate more in the saturation region is to reduce the number of turns, (increasing the volts per turn), while keeping the size of the stack the same. The reason this helps full power efficiency is because you can then use bigger wire, thus reducing copper I^2R losses.

Unfortunately those Tektronix TDS isolated scope channels are only specified to be used with somewhere around 60 or 70 volts of probe differential voltage, although before I read the specs, I used them for phase-to-phase measurements of a few hundred volts. That's why I use those Yokogawa...
I think that what is happening is that the leakage inductance is not part of the magnetizing inductance, i.e. that inductance does not contribute to the flux in the core and so has a voltage drop, even without wire resistance. (I ~think~ I said that right)...
However, a real transformer does...
