DC-DC Power Module, Phase 2 (Prototyping and Testing)

Project Lead: Rick Fishbune

End-of-Project Webinar

  • Presentation and recording (October 27, 2016).  This document is for iNEMI members only.  You must be logged into your member web account to view.
  • iNEMI Specification for DC-DC Power Module (October 6, 2016).  This document is for iNEMI members only.
  • Phase 2 of the iNEMI high voltage (380V) DC-DC project is complete.  During this phase of the project, prototypes of a DC-DC converter were designed to prove out the electrical and mechanical Engineering Specification requirements developed during Phase 1.  The prototypes were tested by the member companies of the Phase 2 project.  The end of Phase 2 project readout included a discussion regarding the highlights of the prototype converter design, the test results obtained during Phase 2 testing, and specification enhancements due to the test results.

Project Statement and Statement of Work


iNEMI held a call for participation webinar on May 13, 2015


There is a lack of standardized high voltage DC-DC power module for cheaper, smaller and higher efficiency solution in the area of high voltage DC (HVDC) power systems.

As such, a specification was developed in the DC-DC Power Module Phase 1 project.  Phase 2 validated and modified the specification based on the prototyping and testing of the power module.

Project Objectives

Prototype the Power Module utilizing the Phase 1 specification.

Test and validate the prototyped Power Module and modify technical specification based on prototyping data.

Will provide many benefits to industry including:

  • Cost benefit - Industry standard product
  • Improvements in time-to-market - Specification and multiple sources for developing the product
  • Introduction of HV technology on system boards that provide low cost power solution compared to the company proprietary expensive solutions and overall cost merit of the power system in a datacenter over the existing AC-DC systems.
  • Cost/Size/Efficiency merits - Narrow input voltage range for 380V DC proposed for higher efficiency and Lower DC distribution losses (I2R) due to lower current.
  • Meeting the future power demand (5X more) - 380V DC distribution over 48V DC distribution.

Project Focus

Results from the prototyping and evaluation on the feasibility of a High Voltage (380V) DC input to a 12V DC output module based on Phase 1 specification and review of modification of the specification based on prototyping..
