Hi

For high power applications like this you will need a two stage approach.

The first stage will be a PFC stage, recommend the UCC28180 controller, following by a dc/dc stage which we would recommend the UCC28950 phase shifted full bridge controller.

Please take a look at the product web pages below which will also guide you to suitable reference designs.
