1kW smps project (based on MicrosiM design)

[MicrosiM]

Hi Microsim!

Here's the PCB with the corrections you said:

high resolution: PCB
Please tell me if it's OK and then I start to build it.

Thank you for your help!
Attila

That looks better now, I advice you to use thick tracks for the AUX output section if you can

 

[cobi]

Hy MicrosiM , could you please send me in pm final schematic or at my mail cobi_lp@yahoo.com please

keep losing track of wich one of these pcb's is the correct one ,,,,,,,,,,one that actually works ok

Very good scope waves,

Why the ETD49 have gap? or you didnt install it yet?

I advice you to upload your images to the POST directly, this will keep them at forums, since we dont guarantee other host life time, please use the ATTACH, you can post up to 20 images PER POST!!!

Please follow with me and update me with your next step

Thanks
