Podcast: Solar-Powered Hikari Supercomputer at TACC Demonstrates HVDC Efficiencies

Engineers of the Hikari HVDC power feeding system predict it will save 15 percent compared to conventional systems. “The 380 volt design reduces the number of power conversions when compared to AC voltage systems,” said James Stark, director of Engineering and Construction at the Electronic Environments Corporation (EEC), a Division of NTT FACILITIES. “What’s interesting about that,” Stark added, “is the computers themselves – the supercomputer, the blade servers, cooling units, and lighting – are really all designed to run on DC voltage. By supplying 380 volts DC to Hikari instead of having an AC supply with conversion steps, it just makes a lot more sense. That’s really the largest technical innovation.”
