My mental capacity was at peak crumbling from being frustrated and burned out for hours just before I met this video. The semester exams kept knocking at my door. I was almost in tears as I tried to keep seated and watch in this dead of the night. This video was like a shot of an anti-anxiety medicine. I couldn't wish for more than this. You're an angel.

I don't think I've ever seen such an incredible explanation of anything. I mean, that animation was just unbelievable! I knew how a VFD worked... but now I REALLY KNOW. Thanks for all of that, much appreciated guys.

Amazing explanation. We engineers have gone through these lessons during our electrical engineering classses, but never had the opportunity to visualize anything in such perspective. Kudos to the creator.

Very good explanation of VFDs. Not mentioned here, but you can also get a 230v single phase in to 380v three phase out VFD. Extremely useful to allow the use of 3 phase workshop equipment when you only have a single phase supply!

Retired robotic & VFD tech here. Absolutely wonderful video. Its done well for what is needed at this part of the training exercise. Had a great time in Aerospace and “other” government facilities working on so many different things.

These are absolutely amazing. I already have learned this stuff, but these are absolutely incredible for a refresher and I show it to people interested too and they can grasp most of it as well. Please don’t stop making these videos!!!

All I can say is thank you Paul and to whoever else working behind the scenes.

God Tier teacher! I work in a trade school and sometimes it's hard for the students to get a grasp of the material, but these videos explain everything so clearly!

the world is quiet here

Your videos are amazing. Even if I have a grasp of the topic, I enjoy your explanation and the videos. Especially because I'm more of a visual person.

I wish I would have had these videos to explain everything when I was going to college 20 years ago!! These are awesome, you make it very easy to understand the principles of electricity and how things in our lives work....Cheers guys!!

I really perfect tutorial. No music, no nervous voice, great graphics, good to understand also by people with other mother tongue. Thank you verry much.

Your videos are amazing. Just throwing this out there. I'm a retired shipyard electrician and something I've seen several times are people mis-wiring tools because they believe that pos and neg switches back and forth such as the light bulb plugged into the receptacle seems to suggest. With that logic, they see no reason to determine which wire in the cord is hot and which is neutral because they believe that AC just switches back and forth. The problem arises when the metal frame of a hand tool becomes energized and they get shocked. It should be noted that at no time is the Earth/Neutral/Ground... side of the circuit 120/240/460...V of a - single/split phase - positive. I love these videos!

One of the best videos I've ever seen explaining VFD. It takes some time to explain to technicians at work, and some experience to fully understand it. Will definitely utilize this... Thank you for posting, Automation specialist.

Thats the best video i've ever come across that explains the VFD sequence of opertaion , good job man

Amazing Video! The animations and the content are perfeclty fitting together to make it understandable and interesting to watch, great Job again.

Absolutely wonderful, I have been a technician on Elctric Trains for years and never really understood VVVF IGBT etc. Now it mostly makes sense.

Amazing explanation. Truthfully I'll have to watch it t a couple more times and take notes but still it's great.

True use of KZread are channels like these ... A million thanks for the lucid explanation and super helpful animation! 🙏🏽🙏🏽🙏🏽🇮🇳🇮🇳🇮🇳

Im working in Danfoss authorize distributor company, this help me so much as a service engineer for this inverter

Awesome explanation! I'm currently leading a team that's in charge of designing a groundwater pumping system that will require a rather large centrifugal pump. The area in question only has single phase power available, but powering our pump will likely require 3 phase power. A mentor suggested to us to look into using a VFD. This video really helped me understand the concept and I can't wait to share it with the rest of my team! Thank you!

Superb video as always. I love to nerd out on VFD’s and Wye-Delta starters. Such simple but ingenious methods.

These videos are awesome. Kudos to the content creator. I have been in the trades for about 5 years and all the schooling I have received left me with gaps in explanations. Thank you so much for the visual aids in helping to truly understand the basics of electricity.

I'm just studying to become a train technician and this video was let's say VERY useful information about the IGBT control over the three phase sinewaves. Thanks a lot! Even our teacher is recommending your channel :)

It was very helpful. I studied this circuit in bachelor but did not know the application. Now at work i am working with VFD modules. Thank you for the simpliest explaination.

I just stumbled across this video, Immediately subscribed. As an electrical engineer, this is brain candy.

Excelente aula, parabéns amigo.

Awesome video. Although I'm surprised you didn't mention CNC machines since it must be the single most common user of VFDs. The whole automation industry is founded upon the VFD to make variable speed, feed, interpolation, and control possible.

Best video of the day. Thanks for the wonderful demonstration of the current flow.

Just let it ripple through your mind. A canned answer is good for smoothing out the gaps. It all depends on what you are filtering - whether content or output.

This is the best video I have seen ever seen illustrating the VFD . Good on you

Your videos are extremely detailed for the length. Nice work!!

I had a pretty good grasp on all of this except how the final A/C waveform was generated. Makes total sense to me now. I work on vintage electronics in my side business and am about to move to a more complex industrial electrical maintenance role at my day job. It's always fascinating to me to learn about the things the modern transistor has enabled us to accomplish, but I'm also still amazed by what we were able to accomplish before that technology existed.

Nice explanation. Just a small correction: From time 4min40sec, I think peak voltage and current has a 90° phase to peak flux, therfore the anmiated electrons are moving at the wrong time. The point of maximum flux should be aligned with zero current (and zero voltage) as dB/dt = 0 during peak flux.

Thank you Paul for this video. I'm trying to build a 25vac 3 phase 400hz supply for a Bendix HSI and this educational video is the kind of video I wish I had been able to see a long time ago. Your explanation is among the best tutorial I've ever seen on any subject.

Hah, they didn't even teach you how to do taxes nor find edible food in the wild, and now all they teach is how to wear a condom and believe what you see on the television...

The video was great. Some corrections: 3:50 No, the electrons in the windings of the generator don't move because the magnets "push or pull depending of polarity." If that was true, holding the magnet still should also make the electrons move, because the magnets still have its polaritiy; but in real life this doesn't happen. Instead, you need a _changing_ magnetic field (in the case of AC motors and generator, it is a rotating magnetic field.) 5:54 No, in general the coils are not inserted shifted 120 physical degrees (also known as mechanical degrees) into the stator. Actual generators have a lot of windings for each phase, so they phase shift is less than 120° mechanical; you may want to read about Ferrari's theorem. What is true is that the output line-to-line voltrages are each shifted 120 electrical degrees from the other two.

I'm talking from Bangladesh, this video is very very important for me because i am an engineer and VFD is very uses in my office (factory). Go ahead with confident.... Thank you so much....!!!

@kevinn2759

The filters in VFD's arent efficient enough to block out all harmonics and when you have a bunch of VSD's this can cause a lot of harmonic distortion. To counteract this, passive and active harmonic filters are installed in the circuit and active harmonic filters in parallel with the VFD circuits work best to filter out any harmonics from the VFD's.

Is this how they control the speed of modern electric trains, and what is the swishing sound from the control circuits on rail traction

Generally, yes. The motors and inverters are a bit different in design due to the torque requirements (same in modern electric vehicles) but the same principle applies.
