First International Workshop on NPES (open to public)
This is NPERC-J’s fourth workshop since its establishment, and its first international workshop on New Generation Power Electronics and Systems. The workshop was cohosted with the Kitakyushu Environmental Electronics Institute (GRIK). Discussion followed presentations by seven Japanese and foreign experts on the future role of reliability science in ubiquitous power electronics.
Time:Jan. 16, 2017, 10:30 to 16:40
Place:Hatsumei Hall, Tokyo
Society of the future will consume 50% of its ultimate energy needs in the form of electric power. Since saving energy and creating energy are recognized as producing the same effect, the technological development and spread of power electronics (PEL) equipment have become essential. With the expansion and spread of PEL equipment, the introduction of cost indicators defining the quantity of energy saved, or “negawatt cost,” is considered key. The workshop has provided another closeup of developments in material-device technology aimed at improving negawatt cost and in the technologies of system integration, mass production, as well as reliability science with applications to total design.
NPERC-J was established in 2014 as an industry-university collaborative body for building an internationally accepted place of innovation with the objective of pushing forward a new generation of PEL research. The Kitakyushu Environmental Electronics Institute was set up in 2015 as an electronics study base conducive to a low-carbon society. This city-controlled research institute is the first of its kind in Japan. For this occasion, since the two organizations share views on negawatt cost, they jointly agreed to hold an international workshop on new-generation PEL and related systems. An outline of the workshop proceedings follows.
