Low-Weight, Low Cost AC/DC Converter for the V-22 2002-01-3187

IPS has designed an air-cooled AC/DC Regulated Converter Unit (RCU) for the V-22 aircraft as a possible replacement of the existing RCU. The Converter receives 3 phase 115V, 400Hz power from the aircraft power distribution system and produces a 6kW, 28VDC output (per MIL-STD-704D). Within the constraints of the existing physical envelope, the design yields lower weight, lower cost, and lower power dissipation compared with the currently employed VRTR (Voltage Regulated Transformer Rectifier). The design utilizes nearly loss-less switching topology, active current sharing, and a modular approach.
