Ferrite core transformer design

[kanaknpk]

Hi

Plz provide the design for the transformer


Input:220Volts,Input Frequency:50Hz,Switching Freq:20Khz
Output:60V/5A
Using Push pull ,Full bridge switching
According to my calculation i have selected ETD49 core

Are ferrite core transfomers used for power supply applications? Have you ever made a transformer? I have seen ferrite core inductors that provide a high value of  inductance, and iron core transformers used for power supplies.

Yes... in SMPS.

Also I'll appreciate your design application formulas to design a switching transformer. I'm working with 1-14V 1-20A and 1k-1M hz, many thanks
