Thanks bro for taking your time to make this video . much appreciated
Beautiful explanation. Thank you
This video is great! I'll definately use it as a reference the next time I have to select a gate driver!
Just one thing that I think you may have forgotten to mention. If you put a 0 Ohm resistor with a diode in parallel with the gate resistor, this would allow the gate to turn off much quicker by providing the current with a quicker path to ground.
Great informative video
You follow Great Scott good
Great Video!
Great video and very well explained. Ill have to check out your other ones. Cheers
That’s great!
Excellent explanation. Thank you very much.
You are welcome!
Thank you very much for the detailed answer!
You are welcome!
Exillent sir
You can also calculate the dq/dt from the datasheet, you have dv/dt and the Gate capacitance
WAO..! Very Well And Number one for me..❤️❤️❤️👬👍👬❤️❤️❤️
Many many thanks
Tq sir ❤
Sir, your explanations are very useful for my project & animation is very impressive. from which software do you make animation.
Hii sir Please Do one video on ferrite bead selection process for EMI suppression...
Look up double pulse testing! It's a test to find out all sorts of useful switching characteristics for switching devices
It's not foolish engineering it's the most powerful engineering ❤
Thank you bros ur awesome. one more thing sir please can you make a video on how to make a gate drive transformer coiling nd how to control an overheating mosfet thank sir
What are the tool you are using for circuit representation?
Your every videos are very informative. Kind make a video on snubber design in SMPS supply.
Sure I will
So, if the gate driver has the capability of being short-circuited the lowest external gate resistor value is 0?
I built a boost converter a few months ago which uses no external gate resistor with a 5A capable gate driver. At the mosfet gate there is a gate ringing of 11Vpeak ~200MHz at turn off. As I don't care about EMI on personal projects, are there any other concerns with this? (11Vpk is within the allowed +-20V at the gate). It already works flawlessly for >1000h of runtime with no problems and even achieves ~97% efficiency.
Please make a video on feedback circuit to measure and control output voltage and current
I have a big question can I use emitter follower to every igbt in and 15kw inverter to help increase current to the gate say 1.5 amp to each gate so I have 24 igbt so for everything igbt 1.5 to everyone so I would give 36 amp to the entire 4 channel is it possible
Hi ,I have 2x faulty 90n33 igbt,is it possible I change with 2x 40n60 igbt only ones I got...ta Steven , 4:52 png.
Nice
Thanks
The explanation is very slow and steady with some thesis, very helpful, but I have a question, from gate driver, the MOSFET/IGBT is voltage driven switch and we don't expect any current (like 1A with voltage 10V) that is depicted in the video... some confusion about this, could you help with this?
due to the charging of input capacitor very high amount of current can flow for short time
Please upload how to make input emi emc circuit
How drive two pic igbt module circuit dayagram for h brize run for 5kw sinewave inverter transformer
Sir your video is top but make video two tipes Hindi and English thankyou sir ji
We will try
@@FoolishEngineer thankyou sir ji
Why would we use a gate resistor as opposed to a pull down resistor from gate to drain?
Bro, Can you make a Setup with One High Voltage Power Supply, One Oscilloscope, And Half Bridge circuits with One Inductor as a Load.....
Using this You can show Proper Results to us (Viewer's)
Working on it!!!
What do you mean by "let's say we need 10v to turn it on and -10v to turn it off efectively"? isn't the voltage at vee 0v or in other words ground, instead of -10v?
It depends, its of at 0 but there may be noisy signals and other issues. Sometimes it will not matter. If you want to be sure drive it below zero.
Calculate? Just put 10R and continue.
😂 right
sir. bleeder.rasister.value.calculation.sir
Subtitles cover the background words ....so irritating 😵
Hindi bhi aati h ya nhi bhai
Ati bhi hoto tuze kyu batau?
Your video is just speaking.in this video I expect to formula and all thing definitely to be expressed.but nothing.just speaking and two formula.?????!!!!
