Very clear explanation , I was confused P+, n+, n- about this, but now clear.Thanks sir.
Sir, how do you obtain the values you use to compare scr and gto, such as 1.5V and 3.4V?
This videos are useful to us sir

isnt the current controlling the turn off and turn on? cuz on scr, if u wont apply current Impulse to the gate it wont open
Good explain everything
Your positive comments motivates me, Thanks and welcome 🙏
Thanks you sir for this amazing explanation
You're welcome! I'm glad it was helpful.
Super sir.i understood easily about GTO
Thanks and welcome

U should expain turn on turn off mechanism separately.
Thanks alot sir.....good way of explaiNing.....

very indept teaching.. good effort
Thank you sir.l understand sir thank you so much sir
Always welcome
@Engineering Funda I think GTO'S must be kept in series to block more voltage. You mentioned it as parallel. Please Clarify me.
Sir nice explanation .. thank you sir
IGCT is not there in your playlist. Sir I have my exam next week. Can you please upload a video on IGCT?
how was the exam XD
Nice explain

Sir in the structure of gto the two doping material are n-type but u placed p+ for gate and n+ for cathode. Is it right sir ?
I have shown perfectly correct structure, you can keep faith in it.
Tks for nice lecture
sir in forward bias characterstics when anide is positive wrt cathode then p+n- and pn+ is in forward bias and in reverse bias junction will be n-p
This playlist has not the video of silicon unilateral switch (SUS)so you can make the video for us
Thank you sir❤

GTO is voltage control device or current control device ? And majority or minority device ?? Plz ansr
GTO is controlled by current
It is controlled by majority carrier
Thankyou sir
Do gto's f/b and r/b same as scr?
Anode+ve wrt cathode f/b
Anode-ve wrt cathode r/b
Yes
amazing course sir
Thanks and welcome
U should clearly explain the operation .
How it functions when while Ton and Toff
Nice 👌 teaching sir

Can u plz explain two points you just read in the video - 1. Turn on process of GTO is not reliable. 2. GTO are connected in parallel to assist in Turn Off.
It seems you are just reading from the book..Thats all
Some of the forward current is stolen to turn off the gto could you please explain this phenomena. Thank you
what IGBT and how can work as punch and non punch
Impedance and admittance ke bare me video chahiye air..
Hello sir, can u plz elaborate what is back porch current in GTO.
Sir please explain about snubber circuit
It is there in my power electronics playlist
@@EngineeringFunda sir may I know the lecture number?
can I make the thyristor using two transistor NPN and PNP
Yeah but you will have to use resistance with npn and PNP transistor
i need the thyristor 400volt 5amp
how make the two transisitor and resistance
can you draw the diagram for me ??
Study 2 transistor model of SCR
Sir can u explain about scr ratings plzz sir
Tq sir .. but can u give the turn on process clearly....
褒める側地様サービス福井市 how many cycles frequency you can turn on off the GTO thyristter?
Please sir make a video gto characterstics anode voltage and gate pulse character.
How about GCS? Is it same with the GTO?
Not much idea about GCS
Ya both are same gto is also known as gcs ( gate controlled switch). Coz gate controll the both on and off state .
Thank you sir

Sir please explain about Thyristor controlled inductor and Thyristor switched capacitor
I will see it in near term
Explain failure causes of GTO
3 time's I chek my earphone 😂😂
What's the 10time faster then scr In which turn on or turn off
Turn off
Sir why gto and scr having low friqency
Thank you sir 😍
Sir what does it means by switching characteristics ?
Turn ON to turn OFF characteristics and visaversa
Thank you sir
Comparison of characteristics between gto and scr
sir how you define the R/B and F/B
Anode +ve wrt cathod is FB and opposite is RB
👏👏

Hello Sir. Do you cover rectification circuit?
What book u referring sir pls reply me😊😊😊😊😇
Khanchandani, Bhimrao and some handbooks of Power
Why construction is different from scr
how negative pulse is helping to turn off
Negative gate pulse can reduce anode current to reduce below holding current which will turn off GTO
Engineering Funda thanks a lot
What is the meaning of n+ in structural representation ?
N+ means highly doped n type material
switching characteristics of GTO ??
Instead of just stating the facts please explain the process why it happens! Otherwise it is just like mugging up!!!!
And it can withstand higher voltage than MOSFET
Actually it takes more current to turn off not to turn on
Sir aapne working achhe se expain nhi kiya.
Ckt daigram leke expain krna chahiye.
Power transistor?
1.75× let's go
At least you should clear the things... You didn't explain why and how of gate terminal then what is the point to make the lectures.
Wehner Summit
Sir turn off time is 10 time
lol look at the state of those fingernails
U didn't explain the working lol 😂😂
If you give +ve pulse then you can turn ON GTO and by -ve pulse you can turn OFF GTO. That is how it works.
@@EngineeringFunda that can be read in a book also...... but how does it actually turn on and or due to -ve and +ve pulse no college will give marks for just writing it will turn off due to - ve pulse and on due to +ve pulse
I don't know what you understands. But this is what the basic working which is there with GTO.
@@EngineeringFunda all I want to know is that what happens within the GTO when there is a -ve or +ve pulse applied to it...... WHY does it TURN on and off by doing so
@@trojanhorse2003 : yes that has to be the question.
Say no to LGBTQ
