I agree and it looks great too! The size is reasonable too considering
what it's doing... Really really cool Kevin I love it. I think it's
actually really neat with the dual coils!

Thanks!
That's right; at 15:1 for 40 watts, its unusual to see a single inductor
boost stage. Like you said, the usual solution would be a flyback
transformer. The duty cycle for this design is around 94% at max load, but
it works!
Why do anything the conventional way if your goal is to power a
With such a high boost-ratio, the other alternative is a flyback converter,
which is almost identical except there is a secondary winding that goes to
the high-voltage side.
Basically to get more voltage out of a boost-converter, you need more
current. There are only 2 ways to do that if
Yup, 2 inductors are in parallel. Couldn't find a single inductor with the
desired spec. I guess my design is sort of atypical compared to the
majority of boost converters.

Very impressive write up Kevin. Like Bill, the first thing that came to mind
was “can I get one?”. I’ve started the resurrection of an unfinished 8 x ZM1350
SmartSocket project and had just done the power supply calculation and realised
I needed 8x roughly 14mA = 112mA for all segments on. I
Thanks Nick! I'd like to do more if I could find the time.

Just wanted to share a nixie related project I've been working on for a few
weeks now. I've got the boards ordered for my latest revision. Looking for
any feedback and to see if this interests anyone.
