@@TechSimulator you are really great please make vdo on extreame fast charging of electric vehicle.... It is future and today's demanding topic.... There is not a single vdo on this please make simulation vdo on it
Thank you for the video, but I don't understand the logic in the current sensing. You create a current reference which is in phase with the grid voltage, but you compare it with the grid current in the reverse direction - the inverter current, which is out of phase with the grid voltage. This will force a regenerative current, and will only work if the DC voltage is an independent energy source. How could this work with a passive DC bus?
it really really really help full, the first time I watched fully clear explanation. thank you so much..could please give an explanation on 3 phase PWM rectifier???
Thanks for your clear explanation. It was a great help to me that I learned from your channel. Could you please explain how we can define the Kp and Ki for the DC voltage regulator?
Explanation is very clear and when we simulate the same system with Matlab 2019A as per the data,the result is not satisfactory.it works good for voltage upto 400. More the voltage the AC-DC conversion becomes discontinuous and power factor also very poor. kindly fix it
@Tech Simulator You are a great teacher and very clear explanation you deserve appreciation. But there is no explanation about PLL Section can you help me? Looking Forward to your reply I am your subscriber plz help me i am in trouble.
Why the constant 400 v is given as a negative input of error signal ? Usually desired set point will be in positive input right ,is there any specific reason for the negative input?
Sir, I have one doubt, During rectification mode, how Igbt will turn on? Because Ac supply is connected to Emitter of Igbt. I am not able to understand this. can you explain Mode1
Sir,thank you for posting this video.Sir,how did you select the values of Kp and Ki in PI controller and Kp,Kr,Ki in PR controller?Can you please share the details which will be helpful for us.
Thank you sir for the video. What differences are there if i need to use the same pwm converter acting like an inverter sometimes? For exemple, in regenerative braking's application, when we need to return power to the grid. Thank you.
@@marvelous9300 Have you able to simulate as achieved required waveform?? Because in my case I am able to achieve required output only if a take Vgrid to be negative..
Sir , the Kp value mentioned as 4.06 is not correct , also the VDC output is not stabilise for coswt , but if you use the sunset , the results are stabilised for Kp value of around 30V . But the grid voltage and current are still not in phase and there exists some phase difference . Can you relook into the Kp value and also if sonet or coswt needs to be used for reference generation.
If you like my work, please do consider subscribing to this channel.Thank you. th-cam.com/channels/58DFky5Fm9AxH9UmWHHYmQ.html
Sir please provide the references how you have calculated all these value of R, L, RC
Another way to improve the full bridge rectifier is by adding capactiors to each diode, I was reading about the "Graetz bridge rectifier".
u are the best man i learned a lot from every your video I want them a lot
thanks a lot

Great work. Just want to find out if it is possible to use any other current for the current control. If yes, how will it affect the control loop?
Thank you for the useful information. I have one question - How do I calculate the inductance required at the input?
Many thanks for your time sir.
Great Explanation🧡
you deserve to subscribe ur channel
thank you.
Sir, in this video you didn't mention kp and ki values of PI controller for PLL Control part, could you please mention it

Sir here which type of pid controller is used?it is Zeigler Nicholas method or other?
Hello sir, I followed same method but didn't get the output as yours, kindly guide me because it's urgently needed for my project submission 🙏🏻🙏🏻🙏🏻🙏🏻
But , the grid current wave form not look like sinusoidal
Sir, I have one doubt, During rectification mode, how Igbt will turn on? Because Ac supply is connected to Emitter of Igbt. I am not able to understand this. can you explain Mode1
What is the range of VDC ref?
How did you find the controller values and R,L,C ?
Still third and fifth harmonic compoments persist in the system even though the THD is within the limits
Is it possible to do reactive power control with that model?
Sir,thank you for posting this video.Sir,how did you select the values of Kp and Ki in PI controller and Kp,Kr,Ki in PR controller?Can you please share the details which will be helpful for us.
Yes it will very helpful for everyone

I have already made the video for inverter. Please have a look
I am getting 0.8V at output. What might be the problem?
sir how to decide the value of reference voltage in controller as 400
Active rectifier is the same as regenerative ?
I don't understand why you control the phase to phase voltage same phase with the phase current.
Bro could you please clarify about how do you get current reference after the PI output and cos wt .what is the relation ..please describe it
This is which version of Matlab sir??
am usign 2021a
What are the values in the PLL section? Thanks and regards

Are you completed PLL section kindly help me i am also stucked in PLL Section as there is no explanationa bout PLL in the video.
Bro i am getting huge currect ..but pill is ok but currect in 500 amps with ocilation why i didnt know
Sir, Please provide the reference paper 📄
I'm working on thesis written please provide me reference so i can use it in submission process.
Thanks
Sir how you have calculated all these please provide the references
Sir,how are you selecting the sample time .eg: 1e-6 0r 10e-6 or 50e-6
This is based on switching freq. if switching freq is very high i try to reduce the sampling time.
@@TechSimulator Thank you Sir.
@@TechSimulator sir what is significance of sample time .how it relate to switching frequency
Can i u show the igbt configuration
In single phase grid inverter u multiply with 1/400 to get Vref but not multiply in this video why?

Just to mention that with sinwt as reference and keeping KP value as 20 helps to get stable output
