For me such values of inductance are way to low as it would be a pain to get rid of the EMI on the AC line.

Obviously different scenarios. But the lesson learn is that it could perhaps be wise to increase inductance a bit, perhaps to 100 or 200uH as this would make things easier on the components, specially at anything below 100KHz.

Looking at those values of inductance I would say it could actually be a good idea to go discontinuous, avoiding the diode reverse recovery with consequent mosfet stresses, or the need for a SiC diode altogether.

Vallery is using some new choques on his 25KW chargers, which handle 25KW continuously, below 20KHz and if memory serves me right, are designed to be water cooled.

I remember he mentioned, at one point, that the now uses a type which is capable of operating at high temperatures, but I don't recall nothing about inductance values. Perhaps he could be a good choice of knowledge regarding this matter.
