When you say at the end that they cancel each other on even harmonic, how is that so? The first positive peake (of 100 HZ signal for example) is constructive towards the fundamental signal, whereas, the second peak is destructive towards the fundamental signal (-Io with 100 Hz positive peak)
I was looking for causes and risks and stumbled onto this. Not that they are causing any issue that I know of---just interesting see on the power line. On the bench I tried a half wave rectifier (50% power) into a "large" resistive load sourced from a non-zero impedance (transformer). It shows up as a voltage asymmetry that's even visible on the primary of my tiny test transformer.
Actually all you proven is that there are no even harmonics for this one case involving a highly inductive load and a full bridge rectifier. This does not consider other load cases. For example if you had the same highly inductive load and a half wave rectifier and ran the same analysis you will find that even harmonics do exist.
On top of an excellent teacher, a great power system expert and scientist, you are also an artist. I eagerly follow your UA-cam channel.
Thank you so much, it's very kind of you.

Wow!!! Excellent explanation. love it
Thank you
please make a video on which harmonics might be positive sequence or negative sequences or zero sequence
Thank you. It's a good point, I will may cover them when I cover the harmonics in the inverters.
