I’m working on simulation of 3-Phase Solid state transformer (SST)
It has three stages AC/DC, DC/DC and DC/AC.
I need help for implementing the 2nd stage on Simulink <DC/DC> for this I'm using DAB with Full bridge
Now problem is that, what should be the valves of capacitor and inductor?
And how to control the IGBT block i.e. gate pulse values
Transformer parameter
Thanks

Hi Robin,
I am also trying to build a SST model in simulink. I would really appriciate if you contact me in this matter.
My email is : Vshahijani@cpp.edu

Hello Robin,
you shoud start with this example to see how to control an IGBT. https://www.mathworks.com/help/physmod/sps/examples/igbt-dynamic-characteristics.html
This site cannot provide you design values for your capacitor and inductor. You will have to determine that yourself based on your design requirements.
Regards,
Joel
