ANDOVER, Mass., 18 March 2011. Vicor Corp. in Andover, Mass., is introducing the IBC048 series quarter-brick bus converter power electronics modules for computing, data storage, networking, and power-over-Ethernet applications. The bus converters provide as much as 650 Watts at 9.6 or 12 volts from a nominal 48 volts within a 38-to-55-volt input range, and operate at as much as 98 percent efficiency, Vicor officials say.
The bus converters are available as drop-in upgrades for industry-standard 5:1 and 4:1 converters, and expand on the Vicor (NASDAQ: VICR) IBC048 eighth-brick modules with 300- and 500-Watt power ratings. The IBC048 series, which uses Vicor's sine amplitude converter topology, is pin-compatible with industry-standard square-wave bus converters, which are limited by switching losses to low operating frequencies, low power densities, and low bandwidth, Vicor officials say.
The VI BRICK bus converters use Vicor's patented ZCS/ZVS resonant converter technology that powers V.I Chips. Switching at about 10 times the frequency of square wave converters, IBC048 modules cut transient response time by a factor of 10, eliminating the need for external bulk capacitors.
