Hello everyone,
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 schematic.
The only difference is that I adjusted the circuit for +36/-36 volts. So, I used a 36v zener and as for turns ratio, (Primary 26 turns of 1.7mm ) and (Secondary 2X4 turns of .7mmX5) are my winding. (ExcellentIT calculations)
I expected everything to run smoothly but after running it, all I get in the secondary output is +/- 2 volts!!
Also the transformer makes an unpleasant noise.
What would you suggest me to do?
Thanks!
Ciro.
