triangular and trapezoidal current modulation in PLECS

Question

I am trying to implement various modulation schemes to dual active bridge (DAB). I have done single phase shift and dual phase shift. I am looking for reference materials for triangular and trapezoidal current modulation implementations in PLECS. Need your insights.

Answer 1

Hello, I came across this resource- perhaps it could be helpful for you: https://ieee-dataport.org/documents/plecs-simulation-files-dab-control-methods

Comments

These simulation files discussed only control methods but not modulation approaches. The only modulation they used is single phase shift.

 

Thankyou,

So I am assuming you are familiar with these concepts and have looked at various resources (e.g., https://imperix.com/doc/implementation/dual-active-bridge-control#:~:text=In%20triangular%20modulation%2C%203%2Dlevel,the%20inductor%20current%20reaches%20zero.), but do you have a specific issue then that you are having in PLECS? Did you try for example, measuring the inductor current in the triangular modulation approach to determine turn-off time? We don't have a ready-made model in this case, but more feedback from you would be helpful to better advise you on this.
