What am I doin here I just search what's better replacement of f16c20?

Sir do you know how to measure isolated voltage with optocouplers

So we need to look at the gate to soyrce vootage and make a oerfect shape like you shown by choosing different gate resistor

This excellent presentation helped me to confirm that I did correctly understand this behaviour. 😊

Clear info, thank you very much 🙏

There's more to electronic design than how it works when new. I'd like to see the results of aging. That electrolytic is brand new. What's it like after it's aged? I believe the high frequencies tend to cook the electrolytic quicker. The ceramic might help slow the aging of the electo as it will handle some of the harmonics. It will also come on it's own as the ESR of the elecro climbs.

👏👏👏👏👏👏👏

Very nice Ali

👍👍👍That's great

Please make video on slope compensation

It's useful,I want to have more and more vedios explian how to cauculate the devise

I can't wait to learn the second lession tomorrow!

Notice this for the first time, but are you at a german company?

worst explanation ever, he proved the formula in the rms case using the formula itself xd!

Hello Sir...I like the way you explain these topics with simplicity......I have a question: How to visualise the common mode noise..when the return is sorted with earth.... Also on the digital circuits of PCB...say a LVTTL clk singal....when normally the return is a DGND plane....how to visualise the common mode and differentiation mode current.... Please give your inputs...

My gate driver circuit burnt. What could be the reason?

Hello Dr. Shirsavar. Thank you very much for the valuable information. I am wondering how different would the design approach be for a two-stage CMC filter??? I think the equations will change considerably am I right? Any design example / resource that you can share?

أشكرك وأقدر مجهودك ، تحياتي لك من تركيا.

Woooow yep guessing 🤦‍♂️ ; Ig = Qg/t(tranistion) once you figure the amount of current apply ohm law R = V/I 🤷🏻‍♂️

I can see that the electrolytic is doing squat, so four 47uF ceramics would be the way to go! :)

dosent the calculation affect fall time

Very nicely explained and demonstrated.

Excellent video and explanations!

hello Sir how to find transfer Function For Totem Pole Boost PFC. and how to proceed for close loop control.

I am lucky that i came across this explanation. Many thanks!

❤️❤️❤️ Nothing better tuen a practice demonstration , Thanku sir

Thank you so much for your teaching. Please introduce a video about the extra capacitor between P and N.

Dear Dr. Shirsavar, many thanks for the video. Due to the real estate problems, what is the negative consequences if we do not balance the inductor over the positive and negative rails?

Dear Dr., many thanks for the video. What is the negative effects if we do not balance the LC filter inductors over the input rails?

Thank you , It is really very useful.

chetta bell and rose watch fake udoo...😁

I heard that Current Mode is easier to compensate compared to Voltage Mode, for there is no complex conjugate poles. Is that correct?

Fabulous video. I recommend all your teaching videos, they are such a valuable resource. Thanks for producing and sharing them.

I have a question this way the turn off time is always faster than the tun on isn't it?

A pleasure to follow your teachings on all these subtleties and techniques of power electronics. Regarding your series on capacitors, which capacitor technologies would be most appropriate for the creation of compensation networks (error amplifier) of SMPS ? Thank you

Awesome. Thank you for this direct explanation. It helps contextualize the control schemes I've seen and clarifies the advantages and disadvantages.

Every video is just great! You really have a gift for explaining these things.

Hi. I have trouble with my halfbridge inverter for induction heating. I get high voltage spikes that i cant seem to get under control, so voltages are building up on the gate of the mosfets. Can you please help or advise?

What a beautiful explanation. I cant skip your video. You make learning more interesting. Thank you sir

Solid video. Just a few new points. Minimum 2 samples per RBW. This scope has a fixed 751 sample span. Thus, 9000/2 * 751 gives a max span of 3.38MHz. So you can't actually sweep from 1MHz to 30MHz all at once. Also, there is a minimum required sample time of 200s / MHz for the EMI filter. I think sample time is in the sweep menu?

Thank you. you are the best teacher.

Useful for me

Also, this diodes keeps the circuit alive during the dead between two MOSFETs.. Agree?

Do electrolytics need to be used to replace electrolytics??? Like if I want to recap electrolyics in a audio mixer or power supply can I use something that will fail clean rather than spilling its guts?

1) An inductor charges ( positive voltages) and discharge ( negative voltage) with the same direction. 2) A capacitor charges and discharges with opposite directions. During switch off, should the negative voltage/current go with the same direction with the "switch on one", from the load resistor -> the anode of the Free wheeling diode instead of counter clockwise?

Nice as always .

Very informative. Thank you Sir.

thank you

I am every time astonished by the ability of this man to explain things in a simple, short and totally clear way. IDK why this channel doesn't have thousands of subscribers.
