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
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...
I am using PI controller and PWM switching to control it but stil its not under control..How can I control output as per reference??

Actually I modified a soft switching buck boost converter as flyback converter. Its not giving expected output for duty ratio in open loop...
Hi
I tried modifying buck boost converter in MATLAB as flyback converter referring to the book Fundamentals of power electronics by Robert.W.Erickson.
But it is not giving expected output as per the duty ratio. The output voltage depends only on transformer. Please help me with this.
Thank You
Actually my circuit was soft switching buck boost converter. I modified it as a flyback converter. I need this to work in MATLAB , then only I can design transformer, controller chip etc for doing hardware.
Sir..
I have designed a soft switching flyback converter and simulated in MATLAB. But it is not working as closed loop.
It is not working in open loop especially boost mode.
What I meant by not working in open loop is that it doesn't give the required output for which duty ratio its...
How about controlling the switches in the screen shot you have uploaded for charging and discharging process??

Actually I am developing a Photovoltaic system. I have modelled a solar panel with maximum power point tracker in MATLAB/SIMULINK. The output of solar panel is...
Hii..
Actually I need to know the parameters of the equivalent circuit and its design.. then I need to know how to control its charging process...everything required to make a SIMULNIK model
Thank You
Hii...
Please help me to make simulink/matlab model of 12V 4.5Ah lead acid equivalent circuit. I also need to know how to design its resistance an capacitance values. Also help me with the charging and discharging control of equivalent circuit.
Thank you
