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!

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.

@randomlymadegoogleaccounts2838 2 года назад

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.

Hello sir one question releted to BMS

@Dc_tech386 Год назад

What is the difference in this from a puchpull they look the same but the north gate diodes or not use in the puchpull

@reptiloidx8942 Год назад

Helo . Please tell me how tochange square signal to pure sine wave gate feed without changing a factory made circuit board ? Thank you .

@tvdylan 2 месяца назад

What pins do we connect to the input signal/voltage and what pins do we connect to the mosfet ??

@mohameddrissi1075 Год назад

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

@FoolishEngineer Год назад

I hope this video will answer all your questions ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nwmqYoBBVbQ.html

@kamilhorvat8290 2 года назад

What's the point of using two NOT gates? Why not simply use input signal to directly switch Q1 and single NOT gate for Q2 switching?

@alexnoggle1874 Год назад

I was thinking the same thing...

@supersilve 10 месяцев назад

Why a mosfet or IGbt sometimes rings at the plateau voltage?

@TB-jl9fr 5 месяцев назад

Very often because of parasitic inductance. toshiba.semicon-storage.com/info/application_note_en_20180726_AKX00066.pdf?did=59456

@hinkosever-koren9911 9 месяцев назад

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

@nitinrastogi724 Год назад

Why did you use both npn transistors. You may use totempol cupplimentry pairs.

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

@FoolishEngineer Год назад

VDD supply would have transient protection or Decaps will take of it

@edisont.picard4112 5 месяцев назад

Wouldn't this work by just conneting both emitters together instead of emiter-collector like you show here?

@coderhex1675 2 года назад

Dude something wrong with last diode section. Current goes over upper diode but should through bypass capacitor not to Vdd.

@spradyuman1794 2 года назад

why Q2 cannot be provided directly with PWM and Q1 given through NOT gate. Using a extra NOT gate will not create problem ?

@FoolishEngineer 2 года назад

extra NOT gate gives buffer timing which makes sure there is no false turn on

@AndrewJonkers Год назад

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....

@FoolishEngineer Год назад

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
