first they have a dc output!
I did say "starting point"
You could remove the
output diodes but then you have the problem that the voltage might not
suit your coil.
I don't yet have a coil - figured that its design would be very dependent
upon what I could do with the power supply, and whether it was used in a
resonant circuit or step-down transformer.
They are designed to operate at a fixed frequency which
may not suit you coil either.
It should be a fairly simple matter to change frequency.
Your coil works best with a push pull drive, many smps are unidirectional.
Any reason it wouldn't work? Optimum efficiency wouldn't be much of an
issue as long as it was within reason.
You say that many are unidirectional - are some push-pull? I could be
selective about what power supply I use (if I could find out which supplies
used Push-Pull drive).
