Good day sir, excellent work indeed. if you design 36 pulse controlled rectifier, can you use the same approach?. by adding 4 thyristor bridge and two 12 pulse generator, what else can you add?. what would be the expression of output voltage as function of firing angle?. how can the harmonics quality at the input and output be improve?
Thank you Samkelo mjuqu. We can design 36 Pulse controlled rectifier by the same approach. Additionally, we can also build them by two 18 pulse converter which would be much convenient to control and simulate. This Paper gives you a good overview of how it can be built-in MATLAB (ijarcet.org/wp-content/uploads/IJARCET-VOL-3-ISSUE-4-1159-1163.pdf). Harmonics can be improved by placing a filter on the source side (To reduce the source current Harmonics). There is an option called three-phase Harmonic filter in MATLAB. Based on the amount of reactive power to be injected you can design it. I have made a video on selective harmonic elimination for an inverter at the load side (ruclips.net/video/Jq86372S4QM/видео.html). This will give you an overview of how to use Harmonic filter in MATLAB. There is also a book called BHIM Singh (Power quality textbook) which is extremely useful to design filters. You can refer to it as well. Hope this helps :)
@@ElectronicsMaddy Thank you very much sir, I have seen this but I didn't find this block labeled F.S having (two inputs F.A and Vi, with output Po) in matlab I can see F.A stand for firing angle which is constant. I don't know what the block F.S is, can you please help me with it. how can I find it in Matlab?
@@samkelomjuqu4300 I think they have combined two blocks. i.e PLL synchronisation block and firing unit block ( 6 pulse i guess) and labeled that as FS. It is possible to combine two blocks in MATLAB so that it reduces the way in which the circuit looks.
Good sir, i have designed a simulation for 36 pulse. but i'm struggling to get correct output voltage waveform, is there a way i could show you my simulation and tell me where i went wrong or what parameters i should use for 36 pulse or firing angle,
Hi bro, great video. If it's in hvdc application and only rectifier is simulated, may I know which load I should connect. Since its hvdc, I should connect R and L right? And what about the values bro?
Hi Maddy, Please do not take me wrong. But i have sent you an email with the attachement of the matlab model *.slx file. Can you please help me to correct the problems/errors which i made while creating this model. I used same steps as mentioned by you in the video.
Hi Maddy,
Do you have a video of 4 or 6 pulse controlled rectifier? or just kindly explain how i can simulate them
Excellent 👌👍
Thank you

Yes, correct. Try with R and L. The load values can be randon initially to start with.

Which generation of Matlab have you used?
2019
@@ElectronicsMaddy Why don't I get the same graph in 2014a? May I get your Email id?
can you share the MATLAB File?
Plz help with same circuit as yours am getting some different output waves
Hi Kiran. Did you try the same steps mentioned? Please send your MATLAB file to electronicsmaddy@gmail.com
@@ElectronicsMaddy sent please check sir
I haven't received any mail. Can you please double check?
@@ElectronicsMaddy Oh yes so sorry I mistyped the mail address will send you in a minute
Sure no problem :)
