Technically that's not an inverter, but ESC. Because I'm pretty sure due to efficiency demands, motors are connected to a battery "directly" via ESC after a BMS. Inverter is rather makes a stable voltage for different abstract consumers. SMPSes radiates more due to improper current path through PCB "antennas", rather than a pulsating current in wires (they have pretty big inductance). Thus even 3-stage EMI filters won't help if let's say a radio module catches this radiation emitted with the ESC "antennas".

Sir could you make video on primary side control and secondary side control for isolated converter

Thanks. Can you do a video explaining common-mode and differential mode in a simple way? 🎉

I guess the high EMI caused the cars that crashed at 5:25 to be exactly the same model, but in different colors. Maybe their is some form of strong attraction between identical car models due to high EMI and this also caused them to crash at the same angle in the center of the street. But what are those things flying overhead?

Hi Prof.

Can you suggest best random noise generator?
It is very good to design jamming transmitter.
I thought maybe one low biased diode in reverse to make a random source generator.
Any idea??

Dear Sam, I had to use a copper shield between the primary and secondary to aviod EMI and partial discharge in a high voltage transformer, and I got a eddy current on the shield. How can I cope with this eddy current?

Sir could you please make video on redundant power supply and change over circuit...

Calling the ferrite "like a bagel" ... LOL never thought of a ferrite like a bagel. :) :)

15:03 ... Instead of a bagel, with a lot of moisture, I'd prefer a dried up doughnut here in the USA. 😛
