Military COTS BCM bus power converter for aerospace and defense applications introduced by Vicor

ANDOVER, Mass., 10 March 2011. Vicor Corp. in Andover, Mass., is introducing the MBCM270F450M270A00 military commercial off-the-shelf (COTS) BCM bus power converter for aircraft, surface ships, submarines, land vehicles, and fixed-site military installations. The device is part of the Vicor (NASDAQ: VICR) V.I Chip power component family. The device operates from a 270-volt DC (230 to 330 volts) MIL-STD-704E/F power rail, and uses the Sine Amplitude Converter (SAC) proprietary topology to deliver isolated power to a nominal 45-volt rail at more than 96 percent efficiency, Vicor officials say.

ANDOVER, Mass., 10 March 2011. Vicor Corp. in Andover, Mass., is introducing the MBCM270F450M270A00 military commercial off-the-shelf (COTS) BCM bus power converter for aircraft, surface ships, submarines, land vehicles, and fixed-site military installations. The device is part of the Vicor (NASDAQ: VICR) V.I Chip power component family.The MBCM270F450M270A00 power electronics device operates from a 270-volt DC (230 to 330 volts) MIL-STD-704E/F power rail, and uses the Sine Amplitude Converter (SAC) proprietary topology to deliver isolated power to a nominal 45-volt rail at more than 96 percent efficiency, Vicor officials say. That is more than 800 Watts per cubic inch of power density with around 0.25-inch profile and one-half ounce in weight.Systems use the MBCM-series bus converters with downstream PRM regulators and VTM current multipliers to drive pulsed-power loads in applications such as radar, as well as in applications like radio and satellite communications, computing processors and ASICs, and memory.

The 45/48-volt-output MBCM270F450M270A00 and its partner 28/33-volt-output MBCM270F338M235A00 bus converters are available in surface mount technology (SMT), through-hole, and thermally-enhanced VI BRICK package versions. For more information contact Vicor online at www.vicorpower.com.
