Thread: SMPS transformer design tool

  1. #1

    SMPS transformer design tool

    Here's a full and complex design tool for calculating the SMPS transformer based on a push-pull , half-bridge and full-bridge topology .
    It has many pop-up tips to help you to use it and correctly paste the values.
    I think that it'll be very useful for many of you , as for the beginners and so as for the guru of DIY.
    Enjoy it!

    I am new and starting with SMPS, so please forgive my ignorance. I don't see the transformer secondary results. What am I doing wrong please ?
    I tried calculating 24V output @ 10 A with VCC 310Vnormal , 240Vmin and 350 Vmax, ETD39 N87 core, half-bridge and full bridge rectifier.
    I am actually using PIExpert from Power Integrations, but I am alway open to new and better ideas.
    Thank you.

    I am sorry, I was so excited because of such an excellent program that I missed that part. By the way, how can copper foil dimensions and thickness could be know from this data ? Would these 6 wires fit the ETD 39 ?
    Thank you again.

    I think that it's hard to use foil in DIY units , but you can recalculate your foil due to diameter and thickness of foil.

    What 6 wires?
    The secondary consists of 6+6 turns of 0.63(diameter in mm) x 5 strands
    And the filling factor yet is a half
