Thank you! My senior design project is constructing a 3 phase VFD for an AC motor using an FPGA board and we are stuck on the gate driver portion to power the IGBTs. The 3 phase gate driver has taken us a considerable amount of hours to implement in our design but I finally see the logic in it. Well explained!
Is there a reason why the MOSFET driver uses two NPN transistors instead of a PNP and NPN pair? Also, in a previous video, you said that the MOSFET drivers are tolerant to negative transients, so I am a little confused about when to use the two schottky diodes.
Have a good day. I really like your contents and learned some things, thanks. Have a question: Why actual signal applied to Q1 Transistor with "2 NOT Gates" ? I thought, creating a dead time between Q1 signal and Q2 signal. Is it true or this question has another answer? If you answer, I will appriciate, thanks again.
2:27 why an extra not gate at the input, would it not be easier just to invert it once at one bjt and leave it as is at the other? Also, by doing this, we do not have to worry about the extra latency
thanks bro for the valuable information , but i have a question , if we use bjt as a driver for a mosfet why we don't directly the bjt for the swittching application because theey are both turning on -off on the same frequency
Perhaps a stupid question from an occasional user of such electronics, but why don't the manufacturers integrate the gate driver and MOSFET into ONE package. Or maybe they do and I cannot find a source for them....
Every MOSFET and its driving requirement is same! we can't just make an universal solution. Although there are some drivers with integrated MOSFETs but those are specifically used in ASICs

Really excellent video
Thank you very much!
What pins do we connect to the input signal/voltage and what pins do we connect to the mosfet ??
Excellent content!
Thank you so much!!
Very good! More please!

Hi ! Is it possible to replace de Shotkky diodes by placing a pull down resistor on the gate of the MOSFET to drive the current to the ground ?
Very very good sir

Helo . Please tell me how tochange square signal to pure sine wave gate feed without changing a factory made circuit board ? Thank you .
What is the difference in this from a puchpull they look the same but the north gate diodes or not use in the puchpull
Fantastic 👍

Wouldn't this work by just conneting both emitters together instead of emiter-collector like you show here?
Dude something wrong with last diode section. Current goes over upper diode but should through bypass capacitor not to Vdd.
Why a mosfet or IGbt sometimes rings at the plateau voltage?
Very often because of parasitic inductance.

Why did you use both npn transistors. You may use totempol cupplimentry pairs.
thanks bro for the valuable information , but i have a question , if we use bjt as a driver for a mosfet why we don't directly the bjt for the swittching application because theey are both turning on -off on the same frequency
I hope this video will answer all your questions

Hello sir
in 6.12, how can the diode sink the transient to the VDD?And Is not it dangerous for the VDD supply?
Thank you
VDD supply would have transient protection or Decaps will take of it

why Q2 cannot be provided directly with PWM and Q1 given through NOT gate. Using a extra NOT gate will not create problem ?
extra NOT gate gives buffer timing which makes sure there is no false turn on
Super, and wich Mossfet driver for MF 20amps You preffer? ;) Well Done
Thank you so much! Please show support to my video with Super thanks.
🙏🎉very nice teach sirji but Hinde language please🎉🙏
Hello sir I like your tutorials, do u have a telegram channel where we can follow u up, it will help
Not yet brother, will work on it
