Re: Converting Switching Power Supply for Inductive Heating


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.

You need to design the coil to suit the job your trying to do, so thats
the starting point.


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.

The smps transformer will only work near it's design frequency, at
least at anything like its rated power.


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.

It's highly likely to destroy the smps.



You say that many are unidirectional - are some push-pull?

Some big ones are push pull.

I could be
selective about what power supply I use (if I could find out which supplies
used Push-Pull drive).

I had assumed you allready had the smps and were trying to find a use
for it. I have worked on industrial inductive heaters and it's not easy
to do, I would forget it if I were you or at least do some research
first.
