Sir

I am designing a soft switching flyback converter for PV application.
I am using a multiwinding transformer as flyback transformer.
I am expecting 12V output as I give 24V input.
But I am only getting 2 V.
I believe that the issue is with the transformer parameters used in simulink especially magnetising inductance (Lm) and resistance (Rm).
Please help me to find out the simulink parameters of the flyback transformer.
The flyback transformer should operate in discontinuous mode.

Thank you
 

You never posted a circuit or design parameters in any of your recent threads. So what's the exact question?
 

Sorry sir

My design parameters are
Vin=24V
Vo1=12V
Vo2=5V (multiple outputs)
Io1=1.8A
Io2=1.6A
switching freq 10khz
resonant frequency 25khz
Lprimary 0.2mH
resonant capacitor=0.2micro farad
coupling capacitor = 2200microfarad

I am attaching the schematic of my matlab model

Thank you
