Electronic countermeasure

The inclusion of airborne electronic attack capability to a long-duration UAV platform provides upgraded electronic warfare support in theater during engagements lead by older or slower aircraft that often rely on last-generation platforms. The challenge is to implement the smallest, lightest solution that is able to drive multiple high voltage sources to an isolated 270V with current sharing.

The power delivery network

A stack of 6 BCM converter modules with the outputs all in series provide 4,242VDC isolation and exceptional efficiency of 97.9%. As is typical in any UAV, the space made available is limited and of irregular shape. The Vicor modular approach allows great flexibility in how to build a power delivery to fit within the platform.
