That is why there are some controlled active rectifier
(using Power MOSFET and IGBT) for the high power AC-DC 
applications. I think IR has quite some device for this
kind of application but they may not be cheap.

Actually I suspect this high power rectifier will have
bad THD which is not allowed to be sold in Europe. But I
guess the OP does not really care about CE mark and other
regulatory requirement.
