Arc Detection in Solar Application

Kummi

Hi,

We need advice in selecting C2000 device for a Solar application with Arc Detection.
Is it possible to implement a Solar application with a single C2000 MCU
which includes Inverter control as well as Arc Detection.

The White paper mentions that Piccolo could be used for Arc Detection,
but if want to control the complete application should we opt for high end Delphino like F28377D?
We need your advice from which device should we start the evaluation.
And if possible please let us know what could be the software structure
if we try to implement this on a single MCU.

Best Regards
Kummi

    Yes, for Arc Detection plus Inverter control you will need the dual core Delphino F28377D.

    Hi Shamim,

    Thank you so much for the quick suggestion.

    If possible could you please let us know on what criteria you have
    suggested F28377D. Is it something like Inverter control with one core and
    the Arc Detection with the other.

    Can we assume if we use two MCU's Arc Detection with F28033($5) and inverter control with F28035($5)
    would be a cheaper and less complex solution compared to the single chip F28377D($19) ?
    or else F28377S single core with a CLA and FPU/CLA units?

    Best Regards

    Hi Shamim,

    Please let me know if there is any comment on the above question.

    I found below white paper mention about using CLA to control the MPPT,
    and CLA could operate independently of the DSP core handling arc detection.
    Which means we could implement both Arc detection and inverter control on a single core C2000
    like high end Piccolo or Delfino F28374S?

    The availability of processors with multiple cores provides further system cost savings by
    enabling a single processor to manage both arc detection and other processing tasks required by solar applications.
    For example, the Control Law Accelerator (CLA) on TI's C2000 Piccolo
    micro-controller platform gives developers a second core for handling Maximum Power Point Tracking (MPPT).

    Also below document released in 2013 has a block diagram showing a single C2000
    used to control the complete system including ARC Detection.

    Just for the reference we would like to know if there is any customer who has successfully
    implemented this kind of application?

    Your suggestion is very much helpful to choose the right device.

    Best Regards
    Kummi
