Thank you, it worked like a breeze!!

thank you

it deesn't work with me

Jai hind sir. I am a 3rd yr engg student. When I try to stimulate I got straight line each of the graph... Please respond me it's a humble request.

Hello Professor, how are you doing? Is everything well with you?

It would have been good if you're adding more examples brother

Looks like u r using wrong formula for calculating the current. 1st is that u don't need to charge the Cgs cap 2 times. 2nd thing when calculating gate current u missed the Cgd cap. The miller effect exists and is based on applied voltage across D-S. Also good luck with ur power loss at gate with the values u have found out.

❤❤❤

Amazing 😍

Sir , how Vce is -ve while calculation by KVL????

how can you get op27 from ltspice

HOW YOU CALCULATD VCB PLZ TELL AGAIN

very nice, could u help me with some problmes Cuk Sepic, i need a mail

This is not the only criteria to select the gate resistor....you missed the most important aspects of selecting the gate resistor

Hi Professor, Can we control the voltage and current of the full bridge converter ?

You could at least mention that the time-domain graph you show is coming from chapter 6 of the book "Switch-Mode Power Supplies SPICE Simulations and Practical Design" by Christophe Basso! Whenever you use existing materials, the least you can do is acknowledge the source, especially when you have copied/pasted equations from the book : {

Did you steal the video from Mano with the title LTSpice Non Inverting Buck Boost DC-DC Converter( Simulation , Filtering and FFT) ruclips.net/video/PJpRGVQBaIg/видео.html ? I thought the context would be different but you did one to one exact same circuit and even your parameter names are the same. I checked who uploaded first and it was not you. If you create a content I find it really disrespectful

helped me a lot thanks

Sir. Please also give examples of where it is used , and real world applications

can you do it with frequency response analysis .fra component

Q. If the voltage of V2 is 10V, is circuit operating?

Please make 4-20mAmp current source

Capacitor

Greeting. requested simulation files to try out but no reply.

Sir i want to learn IC and microcontroller based complex circuit designs explaining in simple way

But generally we take 10 or 15 ohm resistor as gate resistance while doing hardware. I done the calculation as like you but i got a high value of gate resistance. Can you explain why it is so?

Vb =? sir

Hi can you accept my access request ?

very very nice video. thanks for such educational video. keep on making such video.

How to get a input characteristics from this circuit

the idea is that the mosfet should be driven like this: when PulsIN is +5V, Vgs should be 0V, and when PilsIN is 0V, Vgs should be +12V. In reality, in your scheme, when PulsIN is +5V, Vgs is ~+3.73V and when PulsIN is 0V, Vgs is ~ +12V, so you block the mosfet with Vgs ~ 0V for a half period of time (so far it is ok), and in the other half period, when PulsIN is 0V, only then the capacitor C2 is charged, increasing Vgs from +3.73V to ~ +12V, the increase lasts about 523uS, which is unacceptable, and the peak Vgs of ~ +12V is obtained at 1ms, i.e. the maximum frequency def switching is 1kH, for which Vgs is ~+12 V, above this frequency of 1kH, Vgs decreases considerably, and on average you turn on the mosfet 90% of the time with Vgs between 3.73V and ~ 6V.which means RDSon high and therefore Pw on high mosfet, and this lasts for a while until the Mosfet destroys itself..... The only ok option is to use external Vg.

Sir, please provide approve my request for the google drive file

please give access to the file PLZZZ

can you give access for the drive folder

its not working there graph is not seen the same way when tried its shows a constant line.

can you make a video of overcurrent limiting using AC source

Your waves are not symmetrical. Use following conditions: .param D=0.3 .param F=100k .param Ts=1/F .param Ton=D*Ts .param Toff=(1-D)*Ts .param Td=1u .param Trise=1n .param Tfall=1n PULSE(0 10 {Ts/2} {Trise} {Tfall} {Ton} {Ts}) PULSE(0 10 0 {Trise} {Tfall} {Ton} {Ts})

This is awesome, thanks so much!

Thanks for the video, does V3>V2 always?? can we have V3<V2 When I put V3<V2, i dont get negative vltage in ltspice but a value order magnitude mV

Very useful thanks a million

Q1 shoud be 2wAT

Hfe for noise small signal gain and how it amplifies, how to count the the limitations on Hfe small signal gain max. What is Noise Figure and what it is used for? Hertz calculation on inductance difference are in the form of ampere right? So without a bc547, just inductor, resistors and 5 volt source as standard could count be replicated as circuit. What would the circuit look like? The amplifier part was the tricky circuit diagram replica from the transistor only using resistors, capacitors, inductors and no transistors or circuit switches but pure maths on V=IR Kirchhoff's nodes.

how can we control the frequency?

Thanks for this. I noticed that Ton time you used is 1ns, the data sheet does not state 1ns, please how did you get that?
