Vicor Supporting the Power Needs of Today

To meet the power needs of today, Vicor launched the new DCM2322 – Isolated, Regulated, DC-DC Converter. This new roll-out can operate 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. The DCM VIA module provides a higher level of functionality with integrated EMI filtering, tight output voltage regulation and a secondary-referenced control interface. With this launch Vicor provides the next level performance and also innovative technologies to the transportation market.

Ugo Ghisla, Director, Power Systems Applications Engineering at Vicor Corporation

Briefing to BISinfotech during Vicor’s product launch of DCM2322, Ugo Ghisla, Director, Power Systems Applications Engineering at Vicor Corporation explained why power designs are moving to 48V. Ugo also highlighted what has made Vicor a leader in the Rail and Indian Defense sector. He additionally mentioned that Rail will continue to be a focus sector for Vicor.

Key Features of New Vicor DCM2322 – Isolated, Regulated, DC-DC Converter Includes:

  • >500W/in3 power density
  • Up to 90.5% peak efficiency
  • Target markets include rail, military, communications
  • OV, OC, UV, short circuit and thermal protection
  • Array up to 8 units for 960W (no power derating)
  • Most products released to production (43-154Vin, 48Vout end September)

The DCMs can be used in various applications related to Commercial, Industrial and Military grades. A few examples of Commercial / Industrial-grade applications where DCMs best fit in are battery charging, LED lighting and medical devices. Also, applications such as data centers and telecommunications that require huge amounts of power can implement distributed power architecture using DCMs. This can improve the overall power system efficiency and lower the system and operational costs.

The DCM operates on a high-frequency, double-clamped zero voltage switching (DC-ZVS) topology. As a result of high-frequency operation, the size of the magnetics and energy storage elements are reduced. In turn, a revolutionary increase in density is achieved, with the power density up to 1244W/in3. As a result of double-clamped zero voltage switching (DC-ZVS) topology, high efficiency is achieved with efficiencies of up to 93% compared to other DC-DC converter solutions.
