Zoltan's Simulation

[poynt99]

Any comments?

Why the big (and strange) discrepancy in voltage and wave form?

The coil core I used was a 3E6 rather than the 3E5 Zoltan specifies.

This may explain the discrepancies?

The two cores are identical in dimension, but the 3E5 has a permeability of about 8,000, while the 3E6 is about 10,000.

My understanding is he operates the 3E5 core just before saturation, which would mean I might have to decrease the operating current in my version.

Looks like one is probing 'drain' and the other 'source'.
Perhaps one FET is sinking while the other is sourcing?

I don't know, I don't think so BEP. It is strange to be mirrored like that. All the wave forms appear this way. He is scoping across R1, and my R1 is the same. I'll post my schematic as well.

Sorry, some may not have the documentation...see attachment.
