I finally got the correct and precise voltages out of my SMPS. Thank you guys for helping me.
My mistake was the way I had wound the main transformer.
Thank you res_smps.You are right. My winding is parallel! silly me!!!
I'll change the winding like your diagram. As for the output inductor, I
Hi everybody ,
Excuse me I have been mistaken in my first post:my E-mail is email@example.com instead of firstname.lastname@example.org
please can you
Thank you for the reply.. plenty of information for me there.
Im not using a gate drive transformer but I do have the whole board on a 125V 1A transformer
i think that is parallel not series.
sometimes i wound secondary one by one and sometimes together like this picture
I was a bit difficult to explain in English so I try to use the images. my output inductor winding on attachment
The dual secondary winding are in series. just like showed in the attached picture.
Correct me if I'm wrong here, but the way you say that you wound your secondary, it seems to me that the two secondary windings are in parallel instead
A couple things could be causing this. I've only ever seen this sort of waveform when using a gate-drive transformer(not enough drive power) though, so
I was thinking if the voltage difference between two rails is derived from the unsymmetrical transformer winding, so reversing its output would reverse
I made a 50Khz SMPS using the schematic I have attached to my message. I built it using the exact same parts written in the...
