Part Number: TMS320F28034
Dear C2000 team,
First, I would like to clarify what my system looks like.
I have 2 boost power supplies, one is used for PFC which takes AC as input, the other boost takes Photovoltaic Pannel as input(I will call it as boost in the next description) .
This system requires the boost output max power from PV pannel to the load. For example, if load is 1KW, the PV pannel max power is 800W, then boost should output 800W, and the other 200W comes from PFC.
So I choose MPPT algorithm for the boost control (shown as below loop diagram), my MPPT code is comes from HV_SOLAR_DC_DC developement kits.
After enable these codes, I found that the MPPT's output is equal and above Vpv, that means the voltage loop's reference is less than its' feedback, this makes there is no output current from the boost topology even though the load is increased. Could you please help to give your hand on this? Why does MPPT's output looks like this?
Regards,
Jack
