I'm a newbie here and i would be gratefull if someone could point me to a schematic and formulas for an smps project that i could do with my friends.
thanks in advance! =)
Okay, ETD49 core is very good!
Let me clarify that I am here to learn! You are the master here! And I am the disciple ok?
You have mail in your personal box in this forum.
Welcome to forums.
You can check previous posts, you will find the schematic of the 1KW half bridge SMPS.
Also see attched document for more info.
SMPS-Note1 is a good starting point.
We will make that SMPS soon, so please follow up
Hello Hugo.
I cant remember that you asked me for that, however
No intrested people was found into this SMPS, therefore no progress was made.
I will supply you *here* with schematic and BOM, I am glad that you are still intrested into this, this makes me happy!
I dont know if you have access to the parts.
See attached schematic for SMPS, and tel me if you can get those parts.
Also the PCB is ready for this SMPS.
hi microsim
its not that people are not interested in your smps .they do not know about this site .as you have seen
on diyaudio there is always a demand of working smps.as people come to know of this site they will show their interest too.i am also interested in making this smps.
i have couple of questions i have got etd49. could igbts can be replaced with irf450 if not then i have got
some g20n60b3d/irf g4pc50ud can anyone be used.iam also in learning mode.looking for half bridge
topology.but different books different calculations very confused.what formula did you used to calculate your
primary/sec turns.i tried marty browns,abraham l pressmams,col mclymens book.different approaches.
keep up the good work.thanks in advance.

Now I need to know if there is any one still interested into making this SMPS.
If yes, at lease I need to know, or some one should help me out.
Determining the power we need.
Parts availability for all those who plan to make SMPS, like
transformer they have, Mosfets, Wires available, Isolation tape.
all basic things.
In order to start the PCB, Calculating Transformer.
And much more interesting things!
Please let me know

Hi.. I am making a 30 Volt , 30 Ampere SMPS .... using Full Bridge
I am new to SMPS ... could you please send me links to appl. notes for getting started ..... !!
Thanks ... !!
Hi Microsim,
I'm from Indonesia and i really interesting with smps, i have build smps with transistor (self oscilating) cause ic such Ir 2153 etc is hard to find, please teach me about smps.
I'll prepare for build new project smps,
thanks for help
@ cobranet
I will search from psu computer, usually used sg3525.
or i will buy from ebay, i have many ferrite here (rejected unit from electronic manufacture) etd 42,49 it's only USD0,5 (include wire inside hehehe).
I really appreciated if you could share schematic to me at handrich@ymail.com
will create it by schematic and i will post the result.
thanks for kindly help
