Railway DC-DC Converters

Railway DC-DC Converters

Vicor's family of Converter housed in Package (ChiP) DC-DC converter modules (DCM™) modular power components and complete power systems are used for a wide variety of railway applications. The ChiP DCM is an isolated, regulated DC-DC converter module that can operate from an unregulated, wide-range input to generate an isolated DC output. With its high-frequency zero-voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across its entire input voltage range.

The Vicor DCM family addresses many requirements in rail applications, particularly the 100 VIN 3623 ChiP. They feature a wide 43 V to 154 V input voltage range targeted at rail applications using 72 V or 110 V nominal voltages. The family provides power conversion for a wide variety of systems, from embedded computer systems to information displays. With efficiencies approaching 93% and power densities of up to 653 W/in3, the ChiP DCM series offers engineers the capability of using compact regulated DC-DC converters for multiple nominal input voltages utilized by the rail and other industries, reducing the number of parts that need to be supported.
