Really nice video, it helped me a lot, thank you very much! I just could not follow why you chose the gain and PI values of your simulation. Could you explain this with more details? Could you provide the papers from where you got the knowledge?
I did everything exactly same in 2023b version. Its says error. Derivative State 1 in block pv array transfer function.there May be a singular in the solution. Can you help me with this sir
I am getting the correct grid voltage and Dc voltage but the grid current is having so many ripples and also display block is also not showing correct value of power Also How does your powergui block turns Discrete Auto... mine is not changing?
Thanks a lot. I have one question. In Matlab 2022a Fcn is not recommended. Instead of Fcn, Mathworks suggested using the MATLAB Function block. Can you please tell me what I should write inside the Matlab Function block instead of Fcn block? Thanks :)
Hi. I think the reason is that each filter stage will phase shift by 45 degrees at the filter corner frequency . So two stage are need for 90 degree phase shift .this then gives alpha and beta waveforms.
Hello , thank you for best content ! I have some troubles . In 2021b Matlab version , there is no Fcn block . I will use Matlab Function block . What shall I write to here ?
Really nice video! Thank you for sharing! I applied this control methods to diffirent type of dc-dc converter. But my grid current has got a 3th,5th,7th harmonic and so high. How can ı eliminate of this harmonics? I need your help:)

Seems, There's an issue with the control Scheme You have created a reference of 400 V and requested to operate boost at V_MPP. If the Boost MPP voltage and DC Bus voltage are different, there will be a conflict in which control loop to be followed. The solution is- Instead of making 400V as DC bus reference, use V_MPP as a reference voltage. Then the complete scheme works fine.

Incredible content!
Could you try the PQ control for the single-phase too?
It would be good to cover the dc bus and grid current control block in more detail . I was not able to follow all of this
How did you select the dc bus capacitor value?
how u have taken gain 8.5 and 986.8, plz guide

Thanks a lot!!
which video did you make the mppt block in?
is it possible to connect 380V DClink voltage to the grid without transformer using SPWM inverter.
How L, C, L values are calculated on filter ,?
