Hi, thanks for amazing tutorial. I wonder about the plotting of output of PLL block. I fabricated the same model. The d axis voltage is negative. Further the PLL output is not a sawtooth wave but it keeps on increasing negatively. Please help in this regard.
Great video ! What MATHLAB options I need for Power Electronic Simulation generally including Inverters .Is it MATHLAB And SIMULINK only or are there additional toolboxes needed as well ?
Hello sir, i have a question, can we regulate the Vdc voltage and the output iq/id current at the same time? it would be awesome if you can make a video of that. thanks!
thank you for the amazing video! but can you please explain why i'm getting a reference sine wave of 0.5 amplitude instead of 1 (unity) as i'm uing a multilevel inverter and level shifted pwm so some carriers signals are not taken into consideration as the reference sine wave is 0.5...thank you!
Can you please create a video for 3phsae dq control of grid connectrd system? Or can u provide complete guide material where i can read to understand in depth. Also how PI is tuned?
Thank you very much for your videos. I have a question, could we use the PR controller instead of the PI ones, any idea how to do that? I mean to control both Id and Iq, as the same strategy you explained here? Do we need the decoupling terms under this case? Best regards.
PR controller is only used for time domain control signals. In the dq frame a PI controller is the same as a PR controller in continuous domain. You can google the proof
Hello sir. Thanks for the video but iam getting block error when I simulate. It is showing that "the simulink cannot solve the algebraic loop containing dq0 to alpha-beta zero subsystem. The system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues". Sir please help me resolve this issue
Magnitude of input signal becomes half when it passes through a low pass filter twice. To get back the original amplitude we need to multiply it with 2. If you watch mu single phase pll video, you will understand better

Thanks for your work. I have a question, the first order filter is already implemented in simulink ? I don't find it.

Thanks for your teachings, could you please implement the control of a PMSG direct drive wind turbine connected to the grid. Thank you so much!

Hi can u show single phase grid connected model with load . Thanks for the useful videos. keep going.
Very nicely explained...
Nice one .
Thank you
Dear,
Kindly, I tried to use DQ control with Two stage PV system,however, it doesn’t work as should be. Could you provide any helps?
Thanks
Pla contact me at my email

Could you explain SVM for single phase inverter
Nice work dear, thanks.
Thank you
good model! but i notice the reactive power is too large, how to reduce it?

I have already done the vidoe for 3 phase inverter. Please go through mu channel
Greetings, nice work.
please can you share your reference about single alpha, beta generation
This simulation has a problem with output current. I verified a couple of times. still unable to solve it.
I have also checked many times but grid current is distorted in nature
@@jyotikumbhare3492 I also faced the same problem
Thank you very much for your videos.

Could you please give me the link of research paper regarding this simulation.
How can I build two phase sine wave from single sine wave ?
How it will be the circuit if i want to ignore the beta and get the alpha
how can we make a circuit diagram of it? becuase we are going to implement it on hardware
Sir please upload a video on combining this control with mppt
Will upload it very soon
@@TechSimulator want simulation for Dual frequency single phase grid connected inverter plz
Which matlab version is used for this?
How to decide pd and pi value
I got the same output voltage but the output current has many ripples..does anyone know how to solve it?
Can you explain single phase PFC using dq control....
I can understand but i am not good at it. I have gone through all of your videos. Those are really helpful. Love your work.

pls share the simulation
sir, can you provide Simulink files
Please share the reference paper.
Thank you
Is inverter current should be taken for generating alpha current???,,rather than grid current
yes. uisng grid current might generate unstable operating conditions
Can we use the 3 phase front converter dc voltage output (one of u r videos circuit) as the input for this circuit and use this as a bus system.
Yes
@@TechSimulator thanks
Thanks so much
Sir I am getting positive half cycle current peak more in than negative half cycle where I did mistake not able to find
Share the model. I will check
dear sir can u tell what is constant value 10 in ur simulation
Peak value of the required reference current
how did you calculate LwIq value
the L value
Is it the same when we use the photoelectric inverter?.Thanks
You mean solar inverter
@@TechSimulator is it the same for monophasic solar inverter??
I want document for this experiment
what doc?
Great, thx
👍
Can I know the THD of this ?
Sir, how you tune Id Iq PI parameters? Do you tune based on Bandwidth Phase margin?
please correct this model it not gives proper grid current
Thanks
🙏🏻
Vref wave how are it you ???
sorry i didint get
@@TechSimulator Can you show me the waveform of the Vref ?
@@TechSimulator impressive work .could you please give me the of research paper regarding this simulation.
PLEASE SEND ME SIMULINK FILE

Hi,
Why are you multiplied by 2 ?
