Part Number: TMS320F28065

Hello,

Wanted to know is there a code example for 3 phase PFC, as the description given below:

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/171/TI_5F00_3phasePFCandAPFapplicationwithTIC2000MCU.pdf

Had some doubts in dq ordinate modeling given in page no. 18/50.

Also wanted to know controlling for an unbalance load.

Please guide

    Hi Ravi,

    We don't have a released software for that. 

    Had some doubts in dq ordinate modeling given in page no. 18/50.

    [Chen] What are your doubts? any details?

    Also wanted to know controlling for an unbalance load.

    [Chen] I don't quite get your question. The output will be a DC load. Are you asking about unbalanced three phase input?

    Regards,

    Chen

    Sir,

    We are building a system were: APF will be used to correct, power factor of the source. The load can be unbalance reactive or harmonic. Due to which the current at source can be unbalanced.

    doubt 1. dq ordinate modeling given in page no. 18/50: I had worked on simulation where the changes from that model were:

    This control logic isn't working if I create unbalance current in source or load. The correction waveform becomes non-sinusoidal.

    Wanted to know if you can help me on this, as we are building this system with TI-CPU.
