Mitsubishi Electric Installs Railcar Traction System with All-SiC Power Modules on Shinkansen Bullet Trains
Mitsubishi
Electric Corporation (TOKYO:6503) announced today that it has
completed the installation of, and begun testing, railcar traction
converter/inverter systems with all-silicon carbide (SiC) power modules
on N700 Shinkansen bullet trains for Central Japan Railway Company
(JR-Central). These are the first 3.3kV, 1500A traction systems to be
installed on a high-speed train line, according to the company's own
research.
Mitsubishi (News - Alert) Electric has been working to downsize its traction system for
Shinkansen bullet trains. The use of SiC power modules reduces the size
and weight of its new converter/inverter system by approximately 55% and
35%, respectively, compared to existing systems. The weight of the
traction motor, including this system, is reduced by approximately 15%.
The power modules were developed with support from the New Energy and
Industrial Technology Development Organization of Japan.
