Matti and Stewart,

thanks for your answers. Just one question Stewart. You say that :

In effect, the input bridge is a balanced mixer,
multiplying the 20870 Hz carrier by the distorted mains
current waveform.

So the noise conducted to the mains is primarily
20870 Hz +/- odd multiples of the mains frequency.

But, if this were the case, and given that the switching frequency is not
crystal-controlled, shouldn't I see waving lines ? What I see are perfectly
straght lines, no signs of ondulations....

I have noticed another signal, may be Matti has an explanation
for this too :
