Switching Transistor Losses (1/2)

- #178 In this video I start looking at the various types of losses that occur on a transistor used in switching applications. Some of these losses will always be there but others are application dependent. Regardless, when trying to improve the efficiency of a switching circuit, either a power supply or an amplifier, its important to first understand where the various losses are coming from.

Welcome back from Christmas break. You've been missed.
Good to be back! Hope you had fun during your holidays.
Welcome back and a great happy new year.
This year expecting a lot of things to learn from you 😁 mainly power supply control loop.Many thanks for this video
New year and a new great video. Thank you! Keep working like this, you guy are a very good teacher!
Thanks, your time & effort in making this video is much appreciated.
Perfectly demonstrated/Explained and Concise! Thank you for this!
All the best to you and yours for 2023 and beyond - great start to the year getting a notification of another excellent video of yours 👍
Happy New Year and best wishes to you too!
Excellent video, thank you!
Hello! First of all, I would like to tell you, how great your videos are! Your english is also really understandable, so I'll be glad if you keep the high quality videos flowing :) But... I want to point out something, and I hope you don't mind :) Our teacher in high school always poked us as students, because when you saying "MOSFET Transistor" (or BJT Transistor, or LED Diode) you unknowingly say the end two times, since the "T" in the mosfeT acronym already stand for "transistor", as the "D" stands for Diode in LED :)
Regards,
Peter
Hello Peter! I'm happy you enjoy the videos, and well its a fair point you are making with the double word
Thank you for sharing; a new amazing video.
A very good video again!
yay! your back
excellent video!
I love this guy
My understanding is that ganfet has no body diode. Does that eliminate the diode losses?
Hello Sir, I have been watching your videos in the last 3 days, Great job done. Thanks. I have a question. My field of study is computer architecture and I need some basic courses of electronics to recap before digging deep in the simulation part. I have watched the basic parts presented by you but I think I need much more basics. Can you recommend me to one course online that intensively brings me to the page of your explanation? I need to keep watching your course but some basic conceptual understanding missing. Thanks a lot. you are one of the best tutor.
4:28 -- A significant quantity of loss on the transistor? Or the whole system? I think you're saying transistor capacitance will affect driver losses.
Great, i like this. But, please using real component after theory
2:25 the power loss during conduction is the product of the current and the resistance? How about the product of the square of the current and the resistance?
Of course - its current squared; I was trying to say that these are these are the only parameters involved - current and resistance
Why is there a model train in the preview?
Sorry to be a party pooper, you left out g to drain when switching high voltages because of the capacitance from drain to gate. It's funny the that horrid source to gate capacitance helps greatly with this! :) ...yeah I know, this is getting messy.
