Funny enough I just Googled "48V DC Charger" and this was one of the results...
What's needed beyond a rectifier?
No clue here on reading material. You have a large input range and I'm guessing that a mere switch is not in the program. This says that you need a switching power supply or as many are called "universal". Unless you are required to build from scratch, I'd do the "quick and dirty", select a universal power supply with enough "headroom" at the output to allow charging current regulation and design a linear regulator to control the charge rate. If you haven't already done it, you need to evaluate the battery to be charged. If it is lead/acid, full charge is 2.2V/cell, however the charging voltage is a bit higher. As an example, the automotive alternator output is 13.9V .
I hope this helps, comes from too many years in automotive engineering.

200w for your first smps seems adventurous. Check out this site for examples: http://www.poweresim.com/
