Flyback Transformer design gui

[jawale23]

Dear friend's

i have work in flyback power supply topologies but we observed some problems in transformer me transformer is very high heat, and some transformer inductance varition ..?
please give me tips of transformer design..
we design 240vac to 36Vdc/1.2A output

Hi jawale23,

Could you tell me detailed parameter of the transformer, such as primary inductance, core size, turns wire and switching frequency?

For flyback design guide, Please refer to: Fairchild application note AN4137

go to power integration website, they have great tips on transformer construction by hand and how to test it.
