800-V Bus Converter Module Raises the Efficiency Bar
Vicor says the 800-V BCM4414, a 1.6-kW, isolated, 1/16 fixed-ratio bus converter module (BCM) that can operate from a 500- to 800-V input voltage, can deliver SELV output voltages with 97% peak efficiency.
The new 800-V module complements the existing 700-V BCM4414, to create a family of products with reinforced isolation (4242 V dc) 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 come in a 111- x 36- x 9.3-mm Vicor Integrated Adapter (VIA) package that features 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 BCMs are available in either M-Grade (-55 to 100°C) or T-Grade (-40 to 100˚C).
This high-voltage BCM family addresses density and performance requirements for industrial and military three-phase ac power supplies and in high-voltage dc transmission systems for tethered unmanned vehicles.
