Vicor BCM4414 800 V bus converter module

The 800 V BCM4414, from Vicor, is a 1.6 kW, isolated, 1/16 fixed-ratio, bus converter module (BCM) that can operate from a 500 to 800 V input voltage, to deliver SELV output voltages with 97% peak efficiency.

The 800 V module complements the existing Vicor 700 V BCM4414, to create a family of products with reinforced isolation (4242 VDC) and bidirectional voltage conversion capability. The BCM can be easily paralleled into higher power arrays and the SELV outputs can be stacked (connected in series) for higher output voltages.

Both BCMs are available in a 111 x 36 x 9.3 mm VIA (Vicor Integrated Adapter) package, which has integrated PMBus communication, EMI filtering and voltage-transient protection. The VIA’s planar form factor package simplifies heat management and ease of interface to a wide variety of cooling technologies.

The high-voltage BCM family addresses the need for increased density and performance in industrial and military three-phase AC power supplies and in high-voltage DC transmission systems for tethered unmanned vehicles. The BCMs are available in either M-Grade (-55 to 100°C) or T-Grade (-40 to 100°C).
