Result of simulation of LLC resonant converter

Hii, can anyone help me with the waveform of a "Full bridged LLC resonant converter ". After simulation the waveform are quite uneven I don't even know whether they are correct or wrong. Also the filter in the diode rectifier is not working.Can somebody help me find the root of the cause?It would mean a lot as I'm in my final year of master. I have attached a pdf of the model and results after simulation. https://drive.google.com/file/d/1F4JRq5L0NPU1rJyrlITKz0hWSdYcQVBs/view?usp=drivesdk

I'm sorry what was that I didn't quite get it.

Hi @Pallabi

I apologize for not providing a clear explanation earlier. When the provided Google Drive link is clicked, it redirects the user to a "You need access" page. If you have only a single Simulink file, a script m-file, and a data mat-file, it would be more convenient to directly attach them by clicking the Paperclip icon . Interested users can investigate the problem conveniently.

Hii Sam, thank you for letting me know. And the drive link is actually the link of zip file of my simulink diagram. I attach a pdf above of the same. But I'll keep that in mind from next time onwards. Thanks again

Can anyone help me with the simluation?. I have already mentioned the problems on the above text. Also can anyone tell me why the waveforms after simulation do not have the same length?

This is my simulation diagram.

Hi @Pallabi

Have you discussed the matter with your Master supervisor, who possesses expertise in the Full-bridged LLC resonant converter? What was their response regarding the uneven waveform?

While a Simscape model may be convenient for Simulink users who want to skip the formalities of deriving the system's governing dynamics, it can pose difficulties during troubleshooting due to the absence of mathematical equations. Looking at the Simscape block diagram, I also find it challenging to advise where to begin troubleshooting.

Therefore, if you have previously derived the ordinary differential equations using pen and paper, please provide the math model. This will enable interested MATLAB/Simulink users who wish to assist to test whether both the Simscape LLC model and the math model produce the same output responses when subjected to the same sinusoidal input signal.

Hii sir, i took the reference from the above pdf that I have attached. At first, the parameters I chose were completely something i designed after following the steps that are there in the pdf. Bt the result were same as the one i showed. So, I changed the parameter similar to the one in the pdf. Yet the waveform were uneven.
