How Pulse Width Modulation works in a VFD

Pulse width modulation uses transistors which switch the DC voltage on and off in a defined sequence to produce the AC output voltage and frequency. Most VFD’s today utilize insulated gate bipolar transistors or IGBT’s.

Incredible. You just accomplished in 4 minutes what my teacher couldn't do in a whole semester!

[ASHISHMISHRA-begc]

Dude... Your technique for teaching is really cool... Stay blessed man... And keep up the good work🤘🏻

[belalhossen]

Many many thank you for given a valuable speech in short time

[EssayWriting-dupw]

Great explanation, watching from Kenya

[jcardenas]

Jason Bourne explaining some VFD theory...

[richiee.]

Great explained and at least a good start for newcomers! Thanks Mike!

[Jeevaji]

This what I am searching for more than one month

[gonzalocompadre]

Excellent explanation of the pulse with modulation, I have finally understood the operation

[labibahmed-jp]

REALLY NICE. THANKS FROM Bangladesh, I HAVE A QUESTION, WHY IN THE IGBT CIRCUIT USED INBUILT DIODE.THANKS

[serviceteam]

that was kind of so easy explanation pf the theory...guys voice was also heavy and clear

[srvn]

Thank you for explaining it in an easy fashion.

[EmilD]

Great talk about VFD now i fully understand how it works😉 good job👍👌

This control by bus sensing voltage?? Example the output is 678, and data from bus sensing wi set for 400v example, so the microcontroler change pwm for the igbt or fet??

Your description is good, however the characterization of the IGBT as "Open" could be quite misleading. Rather, use the word "Conducting" to prevent misunderstandings as "open" usually means a broken circuit.

easy and quiet explanation thaanks <3

[marekhejduk]

Nice video, but I just still dont understand how the smooth sine wave is made from pulses :( Thank you for answer

[ram]

Very interesting basics I like! Any video on how these frequencies can affect motor vibration?

[berbatsuleiman]

how can we change the width of duty cycle in our applications?

[karthikeyannatarajan]

please make a video explaining how IGBT converts AC TO DC and back DC to AC in regenerative mode and current birection
