Hi,

I am working on 1kW Bi-directional dual active bridge converter. I wanted to apply cascade control loop in my system. I wish to know if you have implemented the same. Also, could you please provide me the control loop architecture of your system?

Hello,

The software development of TIDA-010054 is not fully completed yet. As you can read in the design guide there is a voltage loop and a current loop implemented. These are shown in LAB 3 and LAB 4 of the design guide. There is no cascaded control loop implemented yet.

Best regards,

Andreas

Hi,

I will reach out to our software team and see if they can provide some more guidance on how to implement a cascade control loop.

Are you using a the same C2000 controller (TMS320F280049C) as in the TIDA-10054?

Best regards,

Andreas

Hello Upasana, We do not have any plans to update the controller in the near term. You may modify static inline void DAB_runISR1() in dab.h per your requirements.
