PI Expert v/s Application Notes
Greetings Everyone.I just started making Low Power Supplies and to begin with I started with TOP Series..
I choose TOP 246YN with the following data :
Output Power : 60W
Output Voltage : 12V
Vmin = 165VAC
Vmax = 300VAC
Chosen Core = EI35
K=0.5
Z=0.5
Vb = 12V
Cin = 68uF
After feeding these parameters in PI Expert 9 the values obtained and the values I calculated are not matching.
What do I do ?
Comments
Greetings Mr Kenobi.
Thanks is advance for reply...
The parameters that do not match are Vmin, Lp, Iavg. And Bmax
I Shall upload the file soon....
here are the files.
Since I m an beginer in design power supplies I wanted to design an 12VDC o/p @ 5A.
I chose Top246YN as it is conviently available locally at good cost ..

There seem to be a mismatch in certain input variables, so I would recommend that you go through each input cell and match the designs. I matched the input variables that were different in the two documents and found that the two calculations match.
Can you send me the PIExpert file and a brief description of the parameters that do not match your calculations?
