HV DC powertrain solution
4 March 2009
Power Electronics / Power Management
V.I Chip has announced the availability of a 330 W, 380 V to 48 V DC, 1/16th brick footprint BCM bus converter to complete the powertrain conversion to processor and memory loads in HV DC distribution data centres.
The VIB0002TFJ uses a MHz-switching ZVS, ZCS sine amplitude converter with a high power density and over 95% efficiency, providing over 4000 V of safety isolated 330 W power for downstream loads.
In parallel ‘eco-array’ configurations, 380 V to 48 V conversion is achieved at over 90% efficiency from 10% light load all the way to full-load at multikW power levels. The new BCM provides a vital link in the progression to 380 V DC data centres, enabling conversion to the industry-standard 48 V DC rail.
From there, it is an easy and efficient step to high-current, sub-1 V loads using established factorised power architecture components. The small size and high power density allows a flexible architectural choice for the system designer to locate the power conversion stage per rack, per shelf or even per individual processor blade.
