Part Number: TMS320F280039
Other Parts Discussed in Thread: SFRA
Dear c2000 expert,
I'm using ti's solar library in my projects. Here is my project infomation:
- Topology: BOOST, pv input: 270V~634V, output voltage: 700V~800V(Output connect to baterry)
-Switch freq: 50Khz
-Inner inductor current loop runs at 25khz
-Out pv voltage loop runs at 6.25khz
-MPPT runs at 62.5hz
The inner current loop is stable, because the current loop coef are generated by using sfra tools, and the bandwith is about 2khz. I'm using mppt_incc in my project, currently I found that the time of chasing max power point takes about several minutes, and it has overshoot issue. Can you share some suggestion on how to improve the mppt performance? I'd like to shorten the time of chasing max power point and fix the overshoot.
Regards,
Jack
