What is a MOSFET? How MOSFETs Work? (MOSFET Tutorial)

Published 2022-03-30
Hi guys! In this video, I will explain the basic structure and working principle of MOSFETs used in switching, boosting or power balancing tasks in DC-DC converter circuits, motor driver circuits and many more power electronics circuits. MOSFETs are the most widely used field-effect transistors that operate with voltage control.

We can examine FETs in two groups as you can see here. We had a lesson in which I explained JFET before. I will explain the MOSFET in this trouble. The abbreviation of MOSFET comes from the initials of the Metal Oxide Semiconductor Field Effect Transistor words.

    The amount of knowledge we can get from these videos is enormous . I am 72 and still learning things . I may never use this knowledge but for the young people out there this videos can open up job opportunities or prepare you in the field of electronics . Even if you were not good in math !
  • @L3X369
    Perfect explanation! And The example Mosfet Driver Circuit at the end of the video, made me understand it's use cases even better. Thank you!
  • This is exactly what I needed to know, it really dumbs down the information about the function of a mosfet into digestable and useful information I can actually use thank you!!
  • @RaginKavu
    You forgot about the even less known Boron-Oxide Barium Field Effect Transistor, or BOBaFET. It seems that there is even a whole book about it. Jokes aside, nice video!
  • @Ethio88503
    Thank you God bless you, the more you help to give, the given wisdom you shall receive abundantly !!!
  • @sanelb1147
    So wel explained with the picture of water valve, it makes it so much easier to picture and understand. Hopefully your other teachings are of same quality
  • @saidfarid6382
    Hello dear professor Your lessons are really interesting and crucial, thank you so much for your help and advice,i do appreciate your job,i wish you peace and happiness under the sky of prosperity,all the best. Take care and have a good time.
  • @90FF1
    Your explanation got my novice level head aligned on the MOSFET. Thank you.
  • @rael5469
    I just learned more about MOSFETs in 8 minutes then I did in two YEARS of AA degree classes.
  • @kamranalavi
    Very clear explanation i did enjoy it .i understand hiw they work thanks I'm your subscriber now
  • @josephraj4800
    Good Definitions about MOSFET with Related Animations are Stands Apart , Thank for Sharing and God Bless You Too .
  • As a guitarist, the MOSFET distortion pedal is a very sought after tone. I have no clue why, but it gives the circuit a very unique flavor of clipping and is very popular in the blues/rock/classic metal genres. That's what brought me here.

    Some bipolar transistors can also transmit large currents at high voltages. Note that most inverter motor controllers use IGBT transistors which are a hybrid of MOSFET and BiPolar transistors.
