1kW smps project (based on MicrosiM design)

[sphinx]

Very nice work!

Is a single sided pcb sufficient from an EMI perspective?

hi microsim and ludo3232,

what about adding over current and short circuit protection.and why a seperate board for lm311 and what
it is doing.iam in too.

thanks

This SMPS includes Under voltage protection using LM311 Chip thats why its there.

There is Over current protection into this *Basic* SMPS design, The seperate board for the LM311 + The protection circuit, was to save some space, as ludo suggested!

EMI filter will be on seperate PCB.

Hi all..
I post some pictures of the progress of the SMPS project..

Now i have tested lm317T and IR2153 section and make the protection card..

the transformer is not finished because I do not have good cores ... I ordered them tonight ..

 

[irvynejay]

i'm about to have an interest about this project

 

[ludo3232]

Hi all,

my SMPS is stopped for now, I'm missing parts and I will not have time until January..

Sorry for those waiting..

I intend to finish this smps ... and post all schematics and pcb.

 

[ludo3232]

If someone finds core ETD 49 N87, and can send them to me in Switzerland, I'll pay the core and shipping ... my suppliers are too long delays in Switzerland ..

Thanks

Hi all..

Good news ! I have found ETD49 Cores.. I will test the SMPS soon..

And i have buy a new digital scope.

I postes somes pictures

 

[ludo3232]

SMPS is currently in test.. The first result are no good.. MOS heating is important.. and i have burned some parts..

Ludo nice work.
I'm in a need of a SMPS myself can you help me?I need let us say +-80Volts

 

[ludo3232]

Hello meanman64

I test my smps on load tomorrow and i post first results... and i can help you..

 

[meanman64]

Hoping to hear from you soon

The smps work !

Is actually tested on 800W load.. and is stable ! thanks to microsim for help..

more details later .. Now I testing my smps ..
