 DCM™ DC-DC Converter Module

High power converters for all standard industry input voltages


Vicor-DCM-familyThe DCM ChiP is an isolated, regulated DC-DC converter, operating from an unregulated, wide range input to generate an isolated output. With its high frequency zero voltage switching (ZVS) topology, DCMs consistently deliver high efficiency across their specified input line range. Modular DCM converters used independently or with downstream point of load (PoL) products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point of load. Options include a family of DCMs with tighter output voltage regulation of±1%. The DCM VIA module provides a higher level of functionality with integrated EMI filtering, tight output voltage regulation and a secondary-referenced control interface.

New 10kW AC-DC Converter for High-Density Server Racks

October 16, 2018


Today we announced an AC-DC converter module called the “RFM” that converts 3-phase AC to up to 10kW of regulated 48VDC. This new power component uses a low-profile poVicor-RFM-coldplate-300x200wer tablet form-factor measuring just 24cm x 15cm x 1.5cm, enabling unprecedented power density. It has been designed to optimize the use of space in a rack, and four RFMs in parallel can supply 40kW of power within 1U of rack space, including input-disconnect circuitry, rectification and hold-up energy storage at 48V. The RFM power tablet package also provides adept thermal management for advanced cooling, including liquid cooling.

48V (including 54VDC) distribution is the emerging standard in high-power racks, allowing smaller-gauge wiring and substantially lower distribution losses than legacy 12VDC distribution. In combination with Vicor 48V Power-on-Package (“PoP”) and 48V Direct-to-PoL solutions, the RFM enables dense and efficient end-to-end power system solutions, from 3-phase AC to sub-1V for high-density server rack applications, including demanding HPC and AI inference and learning applications.

The RFM provides a power-factor-corrected, regulated, and isolated DC output with integrated filtering and built-in fault protection for redundant operation. The RFM can be configured to accept worldwide 3-phase AC mains from 200 to 480VAC.



New DCMs Expand Range with Enhanced (±1%) Output Regulation

July 11, 2018



We have announced 25 new DC-DC converter modules (DCMs) with tighter output voltage regulation of ±1%. The new power components allow engineers to drive loads that require tighter regulation with minimal additional circuitry or downstream components.

The new DCMs are flexible solutions for a range of defense and industrial applications such as UAV, ground vehicle, radar, transportation and industrial controls.  A wide operating temperature range is supported, and the DCMs are also available in M-grade, which can perform at temperatures as low as -55°C.

These components are packaged in ChiP (Converter housed in Package) technology, and operate from an unregulated, wide range input to generate an isolated, regulated DC output. With their high frequency zero-voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across its entire input voltage range.

These DCMs offer unrivalled power densities of 1,032W/in3 that, coupled with the minimal number of additional components required, enable engineers to create extremely compact solutions to their power challenges.
