Isolated, Regulated DC-DCs for Rail, Industrial and Defense/AerospaceOctober 10, 2019 by Paul Shepard
Power density, low weight and ease-of-use are critical considerations when designing isolated, regulated dc-dc converter systems for a broad range of robotics, UAV, rail, communications and defense/aerospace applications. The new DCM2322 ChiP family, a lower-power variant of the Vicor DCM3623 series deliver 35W to 120W and are targeted to meet these important requirements.
Packaged in a 22 x 23 x 7mm ChiP, the new series offers engineers wide input voltage ranges of 43- to 154-V, 14- to 72-V and 9- to 50-V with efficiencies up to 90.5%. Vicor DCMs use high-frequency zero-voltage switching topology to achieve leading thermal and electrical performance with power densities five times greater than competing dc-dc converters.
For rail transport applications: Modern rail infrastructure requires a wide range of dc-dc converters to power a variety of new safety systems and passenger services, as well as creating a need for performance improvements in existing systems for both freight and commuter markets. Power density, efficiency and ease of use are critical considerations when designing isolated, regulated dc-dc converter systems for modern rail applications. The new DCM2322 ChiP family is a lower-power and smaller package variant of the DCM3623 family and provides power system engineers a smaller footprint option with input voltage ranges that meet multiple EN50155 standards.
