Other Parts Discussed in Thread: SFRA, POWERSUITE, C2000WARE
I am involved in a project to develop a PFC 3-phase front-end – at a rather higher power than the reference project, but I will come to that shortly.
As part of our investigations I have been evaluating the TIDM-1000 following the steps in the user guide. This has been mostly successful. I had major issues with the source impedance of my set-up, resulting in excessive high-frequency ringing on the input supply – I fitted a capacitive filter (15uF line-line) to the input and got excellent results.
I also have issues with running the SFRA from the link on the main.cfg page of the project – SFRA appears to connect properly and execute a sweep, but only of the default parameters – any changes I make to start frequency or steps/decade are ignored and the same 2-20Hz plot is produced again.
However, the main reason for posting here is to ask this:
As I require a 12-15kW front end, how suitable is the software interface, as it stands, for driving a higher-rated Vienna bridge (higher rated SiC devices, larger passive components)? For instance, assuming the sensing circuits, and the code that reads them, are rescaled correctly, and protection limits re-defined etc, can we continue to use the PowerSuite Vienna project, with its user-friendly GUI and compensation design tools, along with the F28379D controlCARD fitted into my own power & sensing circuit? Or is there a limit, beyond which the code/project would need fundamental changes? Ideally we would like to evaluate our hardware design first before a separate effort to evolve the code into a production-ready state.
Any advice/insights would be gratefully received!
Thanks, Chris
