CCS/TMDSSOLARPEXPKIT: How to charge the battery while providing AC power (combining demo 'PVInverter' & 'PVBattChg')?

Part Number: TMDSSOLARPEXPKIT

Tool/software: Code Composer Studio

Hello everyone,

I am using TMDSSOLARPEXPKIT, and trying to understand the demo programs SolarExplorer_PVInverter_F2803x & SolarExplorer_PVBattChg_F2803x.

One problem is that the two given demos cannot be added together easily (as least from my perspective). I am trying to build a system which has the following diagram. Basically is to integrate PVBattChg (with charger non--MPPT and connected to PV's dc-dc output ) into PVInverter. I am aware that there might be many modifications that needs to be done, and I need to somehow as quoted from other threads "fully understand the program first", but I have no idea how to get started.

So I guess my question is, could somebody kindly teach me how to modify the programs in more detail, or maybe tell me which part I need to focus on (there are too many files in a project!) or get start with. Much appreciate!

 

Best regards,

Yue

    Yue,

    First, I would recommend you understand C2000 MCU, for which you can refer to C2000 MCU Picoolo training

    processors.wiki.ti.com/.../C2000_Archived_Workshops

    This will enable you to be more comfortable around C, CCS and C2000 MCU.

    Once you have grasp of that, I will recommend spending time studying the code.

    You can refer to the Digital Power Library and Solar library documentation inside controlSUITE
    C:\ti\controlSUITE\libs\app_libs\solar\v1.2
    C:\ti\controlSUITE\libs\app_libs\digital_power\f2803x_v3.5\Doc

    I would also refer you to the UG for the individual system that we do support on these designs.

    After which you will be more confident in designing the system you are tasked to do.

    regards
