very nice. May I ask a couple more questions please?

Does the power supply require a minimum load to operate properly?
You mentioned for the transformer 11+11:8+8 turns on ETD49, is it gapped, and what inductance values?

interesting way of using the scope probe as a magnetic field sensor! Do you happen to know the website bcarsten.com? There is an appnote that shows how to build your own magnetic field sensor, with some performance data (parts of it repeated in linear tech's appnote AN67). this is nice to find magnetic "hot spots" in your design...

good stuff, I am tempted to build one myself....

Thanks for the Link, it looks cool

My SMPS needs no minimum load to operate, why it should?

ETD49 Gapped

Will let you know inductance values
Thanks

hi audia.

I think it would be appropriate and mention that this design is not yours but from diysmps.com designed by ludo3232 .......

Default 1kw

Excuse me, this may be stupid question, but can u really get 1kw output from those two irfp460?

IRFP460 can withstand max 20A current.if you have a half bridge configuration then you could theoretically go above 3kw.

Any inductance values? [Wondering if 23.7uh, gapped would be good for half-bridge]
