Power PRM for UAVs and other SWAP-constrained military applications introduced by Vicor

ANDOVER, Mass., 23 Sept. 2014. Vicor Corp. in Andover, Mass., is introducing the power pre-regulator module (PRM) for unmanned aerial vehicles (UAVs) and other military systems designs that focus on small size, weight, and power (SWAP).

Target applications for this power electronics device included those involved with MIL-STD-704, high-voltage 270 volts DC aircraft systems, and high-density power supplies.

The PRM regulator (MPRM48NF480M500A00) is based on Vicor's VI Chip platform, and provides power density of 106 Watts per cubic centimeter and efficiency of 97.7 percent, company officials say. The regulator delivers 500 Watts output power in the same package size as Vicor's earlier generation 120 Watts MIL-COTS PRMs.

The regulator measures 32.5 by 22 by 6.73 millimeters, has an operating input range of 38 to 55 Vin, offers regulated 20-to-55-volt output range (adjustable), and is available in surface-mount and through-hole assembly options.

The PRM regulator is optimized for operation with Vicor's MIL-COTS Bus Converter Module (BCM) in 270-volt DC applications, making it suitable for a wide range of applications including HVDC aircraft systems.
