Please suggest a low cost part in c2000 series.

Other Parts Discussed in Thread: CONTROLSUITE

Hi all,

this is my first post so please be with me if something is not as per post standards.

I have a sinewave inverter project with built in grid and solar charger for load upto 5000VA, company already had this design in MSP430 (LUT based so sinewave generation) but now they want it to be in c2000 (formula based design). 

few days back I referred to a TI distributor and they suggested TMS320F280200DAT but datasheet says it doest has any FPU or CLA for floating point calculation.  Please suggest whether I should go with this or else can anyone suggest any low cost and sufficient capable C2000 part for this design. 

regards

Nishu

    Abhishek,

    All devices in the C2000 portfolio are built with real-time control in mind.  Even the lowest cost C2000 devices, like the F280200, will be able to do control loops for systems such as an inverter.

    The question of what device is best suited will depend on what your solar inverter control loop will be and what other tasks the MCU is expected to perform (like battery charging, ethernet communication, etc).

    I would recommend taking a look at the solar evaluation kits that TI sells (http://www.ti.com/f28xkits) to see if one of these can be used as a way to get started.  Note that the documentation and software for these kits are open-source and freely downloadable through controlSUITE.


    Thank you,
    Brett
