EMC Filter Design Part 6: Common Mode Choke Operation

In this video we explain how a common mode choke works and how the leakage inductance of a common mode choke can help us filter differential mode noise. For further information on Biricha's EMC filter design workshop please visit: www.biricha.com/emc

One of the finest explanations I have ever seen.

Thank you for posting this video it straightened up some doubts about my knowledge of the differences between common mode and differential common mode chokes.

indeed there video series is really the best and highest quality I have seen since. It is very much practical oriented and had helped me to make a better filter for a three phase SVPWM FOC inverter.

Thank you so much man. Respect for you 👏.I had emc exam today and your videos helped me a lot. Appreciate your efforts 👌

[@prashanthb6521]

I can't thank you enough for your videos sir, thanks.

[@cold3lectric]

you immediately went into the part I was unclear about/wanting to know more about (net flux), thanks!

[@anasahmed9190]

This such a great series!

[@BenKistner]

Awesome demonstration!! Thank you!

[@davidanderton2437]

your best video so far

Great explanations

[@daveengstrom9250]

This is fascinating stuff.

I love your videos, but at the end of this one, you show the y capacitors between the common mode and leakage inductance. I guess you did this to make it look exactly the same as if there were separate common mode and differential filters, but wouldn't it be more correct to have the leakage inductance right after (or before) the common mode inductance and the y-capacitors outside rather than between them? A SPICE simulation shows the two cases are significantly different with 1% leakage inductance...

Great explanation.

wonderful video

Common mode choke - flux will cancel each other, correct? Common mode choke won’t be saturated. A little stray magnetic flux will slightly attenuated the main filter circuit. Any thought?

Good evening, but does this choke also work on an antenna with multiple bands? 3-element 3-band directive type? What mix do you recommend to use 43 or 31? Very interesting your video. 73 de Giorgio

Thanks for this video. Do you have a session on the drawing shown @ 5:00?

Sir , are you Indian?
