Variable Frequency Drives Explained - VFD Basics IGBT inverter

Variable Frequency Drives Explained - VFD basics. In this video we take a look at variable frequency drives to understand how they work in electrical engineering and power electronics. We look at where and why to use a VFD or VSD, alternating current, direct current, single phase, three phase, frequency, rectifier, DC bus, inverter, capacitor, pwm, pulse width modulation.

⚠️ *This video took weeks to make* Buy Paul a coffee to say thanks: ☕

These videos are like liquid gold to anyone remotely interested in electricity and how it works. The explanation and animations make it so easy to understand

[o.g.dominus]

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.

[jonp.]

I've taken Physics II, Circuits, and Industrial Electronics classes... this guy did a better job explaining things than the teachers I paid

[lassemunktechnerd]

I have tried to actually understand this for about 8 years.. this flipped the coin. Thanks a lot!

[brysonmartinez]

This couldn't have been published at a better time. I am a current UMaine electrical engineering student and am about to embark on my senior project, which happens to be a VFD I am constructing with a partner, by ourselves. This video helped tremendously, and we will be sure to give you more than enough credit come presentation time. Thank you so much for this.

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!

[iamswastik]

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.

[shaffer]

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.

[trizkial]

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!!!

[evzone]

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.

[JamesSamples]

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!

[ChristianRodriguez-oepu]

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!

[jamiemccoll]

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

[trentaguon]

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!!

[ottokueng]

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.

[thurmanwatson]

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.

[seaningledew]

This is video, and all of the videos on this channel, are hands down the most effective learning resources I’ve ever come across, across all subjects I’ve sought knowledge about. I’ve learned more about electricity in the last 30 minutes than I have in the last 3 years of dabbling. Thank you SO MUCH for producing these amazing videos!!

[tlee]

This is better than the apprenticeship school. One video is worth more than ten thousand words or pictures. I am a retired electrician who is still learning from Youtube.
