i am wondering, if i cld make a flyback transformer (inductor transformer) in pspice and later use it in flyback smps converter and c for simulations in pspice... direct model of such flyback transformer is not available.. if sumbdy cld help me out in dis...
attaching the inductor transformer wich i want

Yes. you should be able to simulate flyback transformer in PSpice.
DO you have design parameters available with you? based on that one can model the transformer model

Let's take a example where Flyback primary is 1mH, turn ratio is 1:2, primary and secondary winding resistances are 1m & 2m ohms respectively

Model would be

.subckt FLBTR 1 2 3 4
Lp1 1 2x 1m
Rp1 2x 2 1m
LS1 4 3x 4m ; Primary inductance * turn ratio *turn ratio
RS1 3x 3 2m
K1 LP1 LP2 1
.ends

Connect Pin 1 as primary + terminal
Connect Pin 2 as primary - terminal
Connect Pin 3 as Secondary + terminal
Connect Pin 4 as Secondary - terminal

Hope this helps.
