Thank you Mr. Lu. This is one of the most complete presentations about EMI issues in PWM converters that I have seen. Very clearly explained and easy to follow. One comment : The questions should have been all at the end, not interrupting Mr. Lu's presentation.

it's my first time to understand well of EMI, CM, DM, dBμV LISN... Thanks so much for sharing these concept so clearly, hope Mr LU can share more about this topic.

Great lecture that recaps all the theory behind measuring and filtering EMI. I would love to see a presentation on designing the filters: stability criterion, attenuation calculation, how to properly design circuit to minimize the filter components...
