    3443.SolarExplorer_PVBattChg_F2803x.zip

    Attached is the software for the closed loop control of the sepic stage, it is based on F2803x however.

    NOte: this is Beta minus version of the software 

    Paste it here

    development_kits\SolarExplorer_v1.0 in controlsuite,

    At this stage this is all i can help,

    regards

    Dear Mr.Manish,

    Thanks for the info.  Its cool.

    Could you pl share any documentation / instructions to run the code i.e., any incremental builds etc. 

    Could you please clarify which port should be connected to the power board?.  The devinit_28035.c  mentions PWM3 as spare

    //  GPIO-03 - PIN FUNCTION = --Spare--
        GpioCtrlRegs.GPAMUX1.bit.GPIO3 = 1;        // 0=GPIO,  1=EPWM2B,  2=SPISOMI-A,  3=COMP2OUT
    //    GpioCtrlRegs.GPADIR.bit.GPIO3 = 1;        // 1=OUTput,  0=INput

    Pl confirm my understanding..

    Also pl suggest which declaration need to be defined for choosing mppt_incc and mppt_pno i.e, I would be using either of them and not both.

    I suppose it could be ported to F28069 exp kit?.  I could not get the DPLIB for 28069 from control suit?.

    thx & rgds

    Hello Mr Manish Bhardwaj,

    I'm a Student and I'm working on the Solar explorer Development Kit with the Concerto Control Card. I want to use the Kit to charge a battery but it`s no program for this function in ControlSuite. Where can I find the Program for the Sepic Batt Charge for the Concerto F28M35H51C to drive the MPPT for the Sepic Stage.

    Best regard,

    Galeh

    Is this the only code you need to get battery charging to work for the F2803x solar explorer kit? I am trying to use TMDSSOLARPEXPKIT

    Hi,

    have you instale Control suite. It`s a tool provides you informations and Documents about any Microcontroller of Texas Instrument.

    You can also get there much example to simulate or to program you Kit.

    Just tip "Control suite" in google search and you will find the new version from the web-site of Texas Instrument.

    I you get any other problem you can send me a message.

    Good luck.

    Thanks, another question. Do you know if the http://www.ti.com/tool/tmdssolarpexpkit

    The secondary controller can run another algorithm like DC motor control


    And can the PV emulator model feed power to the SEPIC stage of that controller?

    So far all parts of the kit are working. However control suite does not include a battery charging project for the solar kit. I used the same files in this thread and it does not compile properly

    Thanks
