Lab 4 Task 4 Synchronous Buck Converter | Power Electronics

[@Thamer03]

I was watching one of your videos and I mentioned in it that you have a channel explaining in English and that whoever wants to see it, look for it himself, and I did not know how to look for it, but today I found it by chance and what a beautiful coincidence Dr. Waleed, you are wonderful. I salute you and thank you for what you are doing ❤️❤️❤️❤️

You're god sent Walid Thank you from Denmark!

وانا عم دور على مواقع اجنبية الكترونية فجأ بتظهر امامي قناتك الدكتور وليد عيسى هي القناة خاصة بلانكلش وانا سعيد جدآ ٱحييك دكتور وليد 👍👍

To the front, Dr. Issa💙💙💙💙💙💙

Hi Dr. Issa, I was wondering how to incorporate dead time in LTSpice? I tried using a triangle wave and a sine to generate a PWM signal and then manually incorporated deadtime for hi and lo side signals, but they don't come out so clean.

Isn't that your UDEMY course ? why is it available for free on youtube ?

bravoooooo from tunisia

دكنور وليد، هل هذه الدروس تابعة لمساق الكترونيات القدرة في الجامعة، أم هو اجتهاد منك مثل دورة الالكترونيات العملية والرقمية...

[@WalidIssaPlusE]

it is a module at university

Replacing a diode by n-channel mosfet including the required gate driver + the pwm control issue,,,,, mmmmmhhh.... i am not sure that can be a wise way in order to increase the efficiency of the converter,

[@tonyavito208]

I think that you need to study more :)

[@nasserbadawi3500]

@@tonyavito208 ok man, you look like someone who know power electronics very well, however I am still learning,,, but are you really want to add n-channel to your circuit in stead of diode just to save some watts over time. Just let me ask you Tony something. Have you ever built a real converter in a real industrial project, do you know how to generate the required pwm? by SW or HW. Do you know that more the 90% of solution based on HW controller such LM5118, do you know how much you will pay in a reall project for your cute replacement to save some watts. I believe if you ever worked in the industry some where you will think totally different and maybe you will learn how things go and move 🙂. However, thank you for your Tipp, i need to learn more, but for sure away from the dynamic on-state resistance of a normally-off power switch😉😊.

Dear @@nasserbadawi3500 I hope that you did not get offended as it is shown in your comment. We learn everyday... in fact we should not stop learning... More facts... this is an educational channel! What if your application is intended to output few mW? And what if you are running a small circuit for medical applications implanted in the body of a human being? Are you willing now to pay the extra cost for such application to increase your efficiency? I apologize if you got offended, I really did not mean to make you feel bad. Sometimes we all act in an emotional way. Take good care, and may God bless you!

[@nasserbadawi3500]

Dear Tony, thanks for your kind. honsely, i did not feel bad from your Answer, that was okey. However, for the Application you already mentioned, the mW power rang, you have absoluty right. Replacement and saving few mWatts in Application such as medical Heart Microdevices will have a huge care and focus, i a gree. Anyway, i am the gay who plays always with powertrains for eCar, where the cost reduction of the BoM is fundamentally required. also before the eCar my activity was focusing on the Railway Traction 😁😁😁. Have a nice day Tony.
