We see from your search that you're looking for information on the term "Active current sharing",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Supplies save space for high power applications from
Schaefer, which we summarised at the time by saying "Schaefer has introduced the C/B 6400 Series of 22kW 8U-high 19in-wide rack-mount DC/DC and AC/DC convertor modules".
A few weeks before,
we featured the news release Front-end supplies bring 48V for distributed power from
Murata Power Solutions: "C and D Technologies has added a 48V family to its class leading D1U-W AC/DC front-end power supply product line".
In November 2006, we covered the news from Sunpower (UK)
concerning its RSP-1000 Series
- take a look at Enclosed switcher boast high power density
which says: "The RSP-1000 Series is a 1000W enclosed switching power supply with power factor correction (PFC) and parallel function for 1U low profile and high wattage applications".
Take a look also at the news release from Powersolve, Supplies front up distributed architectures,
as well as Compact universal-input switcher tops 200W from XP Power,
and 1U high front-end aims for next generation servers from Murata Power Solutions.
