Average current control loop for boost converter using TMS320F2802x

Other Parts Discussed in Thread: CONTROLSUITE, UCC28070EVM

Im working on a universirty project and i need to implement avearge current control for my boost converter(power factor correction) using a microcontroller. I bought TMS320F2802x to use it. i Was trying to find an example from controlsuite. The example i found was PFC2Phil, this example it doesnt debug when i use my microcontroller it says: i copied the information it display when i debug below. Please help me figure out what to change from the code so as it runs on my microcontrller. Thank You

    Hello,

    The unresolved symbol error occurs when a symbol isn't defined in one of the files included in the project. Please check that you've linked in the file that defines PWM_PFC2PHIL_CNF.

    Hi, I'm new in c2000 picollo, can you please show me how do I link in the file that defines PWM_PFC2PHIL _CNF. Thank you

    Hello,

    First you’ll have to search through the files to find where this is defined. You can check through the project’s header files to see which files are included with the # include. This variable should be defined in one of these included files.

    Once you’ve found this file and its location, right click on your project in the 'Project Explorer' and select 'Add Files...' Navigate to the file’s directory and select it. After you select the file, you’ll have the option to copy the file into the project or link it. You can link this file to the project if you do not need to modify it.

    Hello,

    Here is a resource on linker command files:

    processors.wiki.ti.com/.../C28x_Compiler_-_Understanding_Linking

    This should help you modify the given linker command file to fit your project's needs.

    Hi,
    thank you very much. i managed to get the code working. I was following the pdf attached with the project PFC2PHIL, this document it has a step where it says ,"Power the AC input with an AC input voltage within the abilities of the board (110Vac to 230Vac is recommended)." so i don't understand if it means now i must connect my circuit or the launchpad(board). thank you.

    Hello,

    I'm not experienced with this project or the documentation, so I'll ask others with the expertise to answer this question.

    "Power the AC input with an AC input voltage within the abilities of the board (110Vac to 230Vac is recommended)."

    It means that you need to connect the power cable that supplies AC volt to the board, while keeping the AC source off. This AC voltage should be supplied by an isolated AC source.

    Which pdf file you mentioned? Pls send the name of the file and the page number you are looking at.

    Hi,

    Thanks for the reply, the pdf is HVPFC2PHIL, is in controlsuite, page 20 step 25. From the answer you gave me, where to the board to JP2 or where, like im struggling to understand how that is done. Please help me understand how do i do that and where to the board. You help would be highly appreciated. Thank you

    Hi,

    I think i understand what i should do,but i dont havr the board.I bought a launchpad only and it says it can be powered from a computer or with 3.3 V or 5 V.

    Please download UCC28070EVM User guide from TI website. This is the documentation for the PFC power stage used in this project. See page 3 Figure 1. It shows the AC input and DC output terminals. Use this to connect your AC source and DC bus load.
