TMS320F28069: How to use the SPLL on TI C000 Solar Library?

Part Number: TMS320F28069
Other Parts Discussed in Thread: CONTROLSUITE, PMP23069

Hi! I am very new to the C2000 platform and Software Phase Locked Loop Design. I had read the article Software Phase Locked Loop Design Using C2000Tm Microcontrollers for Single Phase Grid Connected Inverter and look through the code on controlSUITE, but I still feel a little confused about the algorithm and how to use the algorithm. i searched a lot but can't find a complete project or example about this topic. Could you help me by share me a complete project or a tutorial about the SPLL algorithm using C2000 DSP?

  • Hello Xinghang

    SPLL is used in PMP23069 reference design to compute the phase of input AC signal. You can find the code of PMP23069 in digital power SDK, solution folder. Please download the latest digital power SDK from TI website. 

    Thanks
