High power charging - industrial motor drive?

I know industrial DC motor drives can be used for battery charging...but I don't see a lot of these drives on the second hand market (or I'm not searching good enough).

Similarly an AC motor drive (VFD) could be used if hacked properly...

Would it even be possible to only use the input side of a motor drive? nice PFC corrected 3 fase rectifier with inrush current limiting.

Unfortunately I'm not capable of doing such things myself (more a mechanical than electrical background), but I'm curious if people here have experience with such use of parts...
