The voltage reversal during charging, which is a 50/60Hz thing probably 
don`t stress the cap too much.
It is the voltage reversal during the ringdown that is the killer. Since 
this happens both with AC as well as DC feed, a rectified charging system 
will not make much of a difference in this respect.
There are other virtues to a DC sharging system, stepless variable BPS 
being the most prominent, although I think you need 3-phase to acheive the 
greatest benefit of it: the lack of need for smoothing caps.
