Isn't it explained at kzfaq.info/get/bejne/r7Clltx5mL2zpok.html and on?

Thanks for input

Not really, connecting the plus input to the reference realizes the feedback summing junction at which the output is compared to the reference. If the positive input will be grounded you will have to do subtraction somewhere else.

The cross over frequency determines the closed loop BW. Or I did not understand your question?

See if these are of help kzfaq.info/get/bejne/bbBmeMeZtbOon30.html kzfaq.info/get/bejne/n9VlmZCcyMqUnYk.html

@@sambenyaakov thanks you Sir

😊

In this case we are talking about the frequency of the "probing" small signal (disturbance) around the feedback loop.

Will try

In DCM, the inductor is charged and then completely discharged. This makes it a current source which, with the RC is first order.

Send me more detailed information. Ican not follow the questions. You can conta t me at sby@bgu.ac.il

Thanks for the comment. I am planning a current feedback control video that will cover inner and outer loop.

Thank you so much sir. I will be eagerly awaiting it.

Also could you give us an example of how to implement dq0 (although this is power systems) to represent the grid and finally connect this with a converter? This part is currently challenging for me to implement.

Dis the operating point around which there is a perturbation od d. See kzfaq.info/get/bejne/pMtpn9KJkpa-p6c.html

Thanks😊

Would you please post these questions at www.linkedin.com/groups/13606756 so members can benefit from answers by me and others You will need to register if not a member.

Google: state space averaging average simulation of PWM

I guess AC sweep is another solution to generate a bode plot which you don't need to know any equation. But you need to understand which kind of transfer function you want to get.

What minute in video are you referring to?

@@sambenyaakov 10:28 - as mentioned

@@cuchulainkailen I am not quite clear about that calculation. Based on the slope formula m = (y1-y2)/(x1-x2) you have a couple of things to consider, the slope value is in DB/dec, therefore x1-x2 need to be expressed in decades. Meaning that x1-x2 = 0.25 dec. From 2KHz to 5KHz there is only 0.25 dec. Therefore based on the slope formula you can say -20 DB = (-35DB - Y2)/(-0.25 decade) therefore Y2 = B = -40 DB.

And increase of output capacitance is generally a poor way to stabilize converters. The ESR increases the ripple and causes a voltage drop under a load step

You need a double zero controller (sometime referred to as type 3)

This will give phase advane

Thank you very much for reply! Another doubt i have is the PM must be checked just only on the crosspoint or on every frequency under it.

Only at the cross over frequency

This is quite interesting, ever tought that even before the corner frequency there were needed phase margin. What if a signal at fcross/2 eg and so gain>1 has 180 phase delay?

This IS a tough subject. Take a break and then watch it again. I am sure you will fully grasp it. It is a very important subject. Not many practicing power electronics engineers understand it. I would appreciate if could tell me a bit about your educational background so I can better understand the reason for my "overdoing" it with this video.

?the link to this video?

@@sambenyaakov I was asking about the link to part 1, though I found it in description. Thanks

How can I do that ???

This IS a tough subject. Take a break and then watch it again. I am sure you will fully grasp it. It is a very important subject. Not many practicing power electronics engineers understand it.

One more thing: try to prepare a primer that will cover just the core of the subject. I would appreciate if could tell me a bit about your educational background so I can better understand the reason for my "overdoing" it with this video.

I can see that it's a very important subject, I'm trying my best to fully understand it, but I think I simply don't even fully understand the basics. What I fail to understand is that at some points I don't really know what you are talking about. It could be because of my lack of knowledge and that you expect the viewers to actually know the basics and instantly see what some slides are about. Was your second comment for Muhammad Adeen? Well, I'll answer it anyway. Yes, I should further research the core of the subject, which I will. Do you have tips on where to start? For my educational background, I am currently studying mechanical engineering at the Technical University of Delft. However, I have a heated passion for electrical power systems, your subject of expertise. I know that everything you discuss is very important in power electronics design, therefore I want to understand, sometimes even too fast. I don't think there was any overdoing. I do think you assume your viewers to have atleast seen these topics a couple of times before. There were some terms in this slide I had literally never heard about or even the basics of them. So on somethings I can't put a connection to, there isn't a well established link in my head. I will make sure to further research this topics and rewatch the videos. Therefore your effort has not been for nothing! I will understand this topic completely, I promise.

Hi, Thanks for sharing your concerns. The background required is Bode Plots and Laplace Transform and Domain or in general: what is usually referred to as Theory of Dynamic |Systems. Your self improvement efforts are commendable.

Ah, thank you very much, I will come back when I understand those subjects better! Yes, I like everything about anything that handles great amounts of power. Especially with the rise of electric cars and stuff like Tesla, I think it's very important that these subjects are well understood, even as a mechanical engineer. You are helping me there.
