Thank you :)
Amazing explanation. Thanks bunch
Are there good tutorials for that software?
Thanks a lot🙏🏼👏
Great video thanks.
Sir please upload more videos... Your videos are really helpful
It helped like anything else, I can't thank you enough with words,, God bless you
Omg this is Gold,,,,,Thank you so much, God bless you
Good explanation Thanks! Do you not need to null any voltage or current sources in the circuit before calculating output or input impedance?
Hello. Can you tell me why you didn't include the parasitic resistance of capacitor in the boost converter when you did so for the buck converter previously?
Please continue with the Part 3. I wish you can show the additional circuit to prevent the inductor from saturating.
Could you please explain me What is S? it is 2 times pi times F?
"Bulk Converter" as the title claims? Apparently not. According to 0:40 it's about "Anaysis" of a BUCK "Conveter". So I guess it's supposed to be ANALYSIS of BUCK CONVERTER. Unless it's about any sister of Buck Conveter, which is perhaps a Bulk Converter.
We've got some schematic speedrun over here!
Thank you for valuable information sharing with us
If you want to use LT1016 with supply 0-5V, Vin should stay in 1.25-3.50, so if you want Vin till 0 Vcc_negative should be best -1.25V. Great Video. It helps me a lot.
Really good
super lecture, as always
Professor you are best
Thank you professor!!!
I am designing a 12V to 5V buck converter with type 2 compensator i am facing a problem that when i changed the source voltage the output voltage also change while in the closed loop buck converter by changing the source voltage and load the output do not change according to load prospective my output is correct and in source my output change Anyone can help?
Very thorough and tangent explanation! Thanks a lot.
Thanks ....
Thank youuu
@14:45 Transfer Function has the pole-zero mix-up. Zero Results into a +20dB & Pole results into -20dB cancelling out and provide a flat gain due to Rf/R1//R3...Overall excellent analysis....good way to look at transfer functions from circuit point of view...
I confirm as well.
thank you Mark Ruffalo for explaining this so well
wonderful lectures, it is really fantastic
Greet job thanks, what the schematic looks like
Sir, can you explain how did you set the compensation op amp values?
can you please help me so I can understand this video, otherwise its very confusing
The C's impedance is 1/sC or 1/2pifC. when 1/sC=R, a transition point, also called -3dB point in power, since the output is exactly 50% of input voltage. For power, dB=10log(Pout/Pin). For V, I or R, dB=20log(Vout/Vin). So for Vout/Vin, 1/sC=R is -6dB on the vertical scale or 20log(0.5Vin/Vin)=-6dB. Why -20dB, decade in frequency in a factor of 10. If f_pole=1kHz, one decade is 10kHz. Simulate RC circuit in LTSpice with R=10k, C=0.01u, f_pole=1/2piRC=1.591kHz. If you check the dB value at 15.91kHz, you will see the Vout/Vin in dB will be measured at -20dB, hence the output ratio in voltage is falling at a rate of -20dB/dec. At 159.1kHz, the dB value will be at -40dB, because it is 2 decade awa from f_pole. Hope this helps.
@@leiaz6762 I'm so sorry, I thought I responded to this right after, this was very helpful thank you so much for explaining, I really appreciate it
why are we looking at when the impedances of R and C are the same at 5:22? Why is the result -20db down? Why do we fix the values and call it a pole?
Just saved the life of a master's student in Spain! Thank you very much!
Hello, could you pls send me the LTSpice model? louis_song@126.com Many thanks!
Very Very helpful. Thank you!
Thank you!
Very Nice work
I need to know why he pinned on IL1? Is that the load current ?
hi, how an IGBT should be modeled in LTspice? there are PIGBT and NIGBT amonge components of LTspice, when I am using them, i got the error, that model is not defined. can you please help me how to model it?
Thanks a lot, it is very useful.
Hahaha
This is awesome, Thank you very much...
Thank you very much for sharing your knowledge about power electronics! I recently got interested in building a Boost converter, but being a mechanical engineer it's not easy to get deep enough into this topic to not only understand but calculate and build a Boost or Buck converter. I highly appreciate the time you put into this video! PS: In the video you said that you wrote a book about boost converters. What's it's title? Greetings from Germany, Marv
They are fantastic, Thanks
please keep up the good work. thanks for these fantastic lectures
Thank you for a detailed video. Can you do a boost converter
and also how do you implement it using real components?
where's the video prior to this?
Thank you so much for the very nice explanation! It was very helpful.

Very useful and interesting presentation. A little hick-up at 14:00 where you mix up the pole and zero .
