Intermediate power bus converters

2 March 2011 Power Electronics / Power Management

Vicor announced the introduction of the IBC048 series of VI BRICK Intermediate Bus Converters.

Available as drop-in replacements for industry standard eighth-brick and quarter-brick 5:1 and 4:1 intermediate bus converters, initial product offerings include 300 W and 500 W models, providing 9,6 V or 12 V outputs from a nominal 48 V input with a voltage range extending from 38 V to 55 V.

The new converters utilise the same ZCS/ZVS engine that has powered V.I Chips into high-performance applications with tier-one customers. Switching at very high frequencies, IBC048 modules cut transient response time from 200 to 20 microseconds, eliminating the need for bulk capacitors. High density and conversion efficiency benefit applications such as computing, data storage, networking and Power-over-Ethernet.
