Ideal for Applications such as Tethered Unmanned Vehicles and Power Distribution Systems

Vicor has expanded its bus converter module (BCM) lineup by introducing a new fixed-ratio high-voltage bus converter. The newly launched 1/16 700V K BCM delivers a power level of 1.75kW with 97% peak efficiency at a power density of 700W/in³.

The device is offered in a robust 4414 (111mm x 36mm x 9.3mm) VIA package with excellent thermal performance, featuring chassis or board mount options and 4.3kV galvanic isolation. The rugged VIA package also provides integrated PMBus communication, EMI filtering, and voltage transient protection capabilities. This flexible module can be easily paralleled for higher power arrays. Additionally, BCM outputs can be connected in series for higher output voltages.

The BCM is a highly suitable power component for a wide range of applications such as tethered unmanned vehicles, power distribution systems, and three-phase front ends. BCM devices also serve as unregulated isolated front ends, supplying power to Vicor's ZVS PoL buck/buck-boost regulators or PRM and VTM modules in factorized power architectures.

The newly launched high-voltage BCM series is available in temperature grade options of "T grade" (-40˚C to 100˚C) or "C grade" (-20˚C to 100˚C). Products meeting military-grade specifications (-55˚C to 100˚C) are scheduled for release in the second half of 2017.
