TMS320F28375D: HV_SOLAR_DC_AC_v1.1

Part Number: TMS320F28375D
Other Parts Discussed in Thread: CONTROLSUITE, TIDM-HV-1PH-DCAC

Hi There,

I would like to know if it is possible to port the HV_SOLAR_DC_AC_v1.1 code from F28035 MCU to F28375 MCU?

I've had an initial attempt and the code compiles, however I have not been able to link it yet due to my not creating the memory map files yet.

I moreso wanted to know if it was possible before diving too deep into something that may not be possible.

Thanks in advance.

Robin

    Robin,

    Yes it is possible, however that code is in controlSUITE and will not be moved to SDK, i.e. it is not maintained.

    Main challenges you will face will be ADC config and trigger.

    Also, in my opinion, it does not set you up for success because it is written in assembly. I will highly recommend you look at the code we have for TIDM-HV-1PH-DCAC it is very advanced and written in a very scalable manner.

    Hi Manish,

    Awesome, thankyou.

    We are looking at developing the code using the TIDM-HV-1PH-DCAC, however as our baseline started as the HV_SOLAR_DC_AC_V1.1 we wanted to confirm a "Plan B" as a risk mitigator in case we couldn't get the new code to work with the old inverting topology.

    Are you able to confirm if the TIDM-HV-1PH-DCAC is flexible in nature to be altered to operate the same topology of the older design, except with the SDFMs and F28375 implemented instead? e.g. LC back end on each leg instead of the LCL on the active leg?

    Regards

    Robin

    Robin,

    As we are fully programmable , there are no limitations. 

    You can use the filter stage as in the older solar_dc_Ac design , you will need to update the PWM driver for it. We even put a jumper for you to install the other L if you wanted to test things on the EVM.

    Great news, thankyou

    We don't have access to the older TI EVM, it is no longer available from Digikey.

    I'll have a think about how to progress from here.
    Again, many thanks
