Warm regards too Mr. Andrew Lebon.
I appreciate your time and effort for
giving me the schematic of self oscillating
SMPS which is nice and simple although
some of our co-members gave negative comments
about it. I still have to make circuit analysis
myself to know if those problems are true or not.
Anyway here is my email where you can send me the
the details...kiko_antonio71@yahoo.com...Best wishes
to you and Goodluck to our common goal!.Thanks too to all
my co-members who gave response.

[adamkaktus]

i know that it is old topic, but did you assembled this SMPS? does it work properly? Can i have copy of files to make it for my own?

[kikodemy]

ok sir adamkaktus..i already made my own version of that smps...but it's been undergoing the series of testing yet, to make it really ok..it is half bridge, offline with 220v input, using
k2611 mosfet..is this fet available in your place?....the output is 50v and i still have to modify the winding to make it dual +50v, -50v...because the transfo that i used was the original ATX power supply 500w transfo with EE35 number...and it was very surprising becoz the 12v became 50v (without center tap terminal)in my design..tnx
