Does the NPC inverter works with the control design you used for 3 phase standalone inverter for balanced and unbalanced load? Also will you consider making a video on inverter switching design from grid tie to islanding?
kindly, explain how to calculate the filter values (L&C). You directly put the values so we cann't able to design the inverter for some other ratings. Pls explain the parameter design too. It will be helpful for us.
Thanks for the video. Very good explanation. Can you please make some videos on Multilevel inverter fed induction motor drive? For example., 5 Level NPC inverter, Cascaded H-Bridge inverter fed Induction motor using vector control or direct torque control. I highly appreciate your work. I have also recommended my students to follow your channel for better understanding of inverter control. Thanks in advance. Go ahead.
Can you please also do the 1 stage grid connected NPC inverter. I'm having issues in designing the outer voltage control loop design following the design you mentioned for the 2 level solar inverter. Thankyou
This is very informative & knowledgeable video. But, I a doubt on PWM. You considered one carrier is (0 1 0) & other one is (-1 0 -1). It will be very helpful if you share the concept of it with us. Thank you.
I've emailed you but there was no reply. Can you please make a video or refer to some literature about how to calculate PI controller parameters. That'll be very helpful. Thanks

This will not work OK for a practical system with unbalanced grid/load because you neglected to apply voltage balancing to the inverter DC bus. You should feed the Vc1-Vc2 error to a third PI controller and feed the output to the zero vector port of the final dq0 to abc transform...
I designed this simulation and verified it three times. I found everything is fine according to this video but the output current has oscillations. I found three-level voltages at inverter output have to peak voltage ripples. How to solve it..... Please help me... Thanks in advance
He used very large capacitors with ideal DC source and balanced grid, which is why the control worked despite the fact that he forgot to apply capacitor voltage balancing control... UA-cam is not a good place to learn electrical engineering...
thank you very much it was really helpful. i will appreciate if you can help me with the simulation of 5 level modular multilevel converter grid connected.

hi there would i be possible for u to share the stimulation file?
thank you so much Sir for making videos which are really very helpful and conceptual and also brings us the MATLAB as a interesting software

Can you also do droop control?
For parallel operation?
Yes if possible or just for single system
Hi, can you explain the differences and uses of 3 level over 2 level in detail ?
Thanks for the videos man
I was curious, thought it is a bit outside of what you're doing, how to design a PV +Battery off grid system
Cheers
I am preparing videos on PV inverter grid battery etc. will upload very soon
What did he do in 05:32
Can you use p.u values for the controller ?? if so can you explain how it can be done!
Gracias por el aporte excelente
why did you set -205 as reference/
Instead of diode can i use igbt? And this application will be ANPC Inverter
Sir i have made 3 level npc but i am getting 9 level output out of inverter.
I've emailed you but there was no reply. Can you please make a video or refer to some literature about how to calculate PI controller parameters. That'll be very helpful. Thanks
I am also looking for it

Do you have any tutorial for ANPC inverter?
@@vasavisai1890 unfortunately not. I'm combining the knowledge of this book and tutorials of this channel
Sir how to model dc-link as a current source ,also how to find value of C for dc link?
Sir what about grid current and inverter current comparison???
It could be use as ACDC rectifier?? If yes, how does the control change? Excelent video
Look for the Vienna rectifier, which is a three-level AC to DC converter. Control is different.
This will not work OK for a practical system with unbalanced grid/load because you neglected to apply voltage balancing to the inverter DC bus. You should feed the Vc1-Vc2 error to a third PI controller and feed the output to the zero vector port of the final dq0 to abc transform...
are you trying to say he should apply VOC control scheme to balance the voltage at the inverter DC bus?
@@kamadjesadjiedjienaallen9259
yes. DC bus balance can be achieved by modulating a dc current component into the dc junction as in a Vienna rectifier.
brother can you make this converter bidirectional for EV charging?
Thanks for your efforts man ... what about the capacitor control and can we doing variable reference?
Sorry brother. I didnt get your question?
Bro i mean if the source is varied dc input how can i got the reference current the second how can i make capacitor balance control
@@ahmednaji635 same doubt, how tl select the dc link capacitors?
Is this design is Space Vector PWM (SVPWM)?
??
@@arminhasanzadeh5161 No, it's SPWM
No
@@TechSimulator Can you teach us how we can implement SVPWM?
Sir please also show how to find THD for this 3 level NPC grid connected inverter
Thanks for your effort. Please can you provide where is the equation of the control come from? I mean
Vd + Ed + wL×iq
How can we get it ?
This is the basic kvl equation. Grid voltage is equal to sum of inverter voltage and voltage drop across the filter inductor.
sir in this why we are fixing current to -205 sir
What about for a single phase?
??

Reason present behind '2/800 'gain block.
pls......thnks in advance
I am interested to know about it. Please comment the reason.
@@vasavisai1890 It stems from the modulation index (duty cycle) or simply it's the relationship between between Vdc and Vinverter
I designed this simulation and verified it three times. I found everything is fine according to this video but the output current has oscillations.
I found three-level voltages at inverter output have to peak voltage ripples. How to solve it..... Please help me... Thanks in advance
did you solv it ? i have the same probleme
@@mouhamedyou No man
please if possible make parallel inverter connected to grid with droop control
