6.5kV Full-SiC Power Semiconductor Module Developed

– Will allow for smaller and more energy-efficient power electronics equipment in railcars and power systems –
January  31,2018
New Energy and Industrial Technology Development Organization (NEDO)

As part of a NEDO project, Mitsubishi Electric Corp. has developed a 6.5 kV full silicon carbide (SiC) power semiconductor module, which has 1.8 times greater power density than a conventional silicon (Si) module, making it the world’s highest power density. The advance was made possible by implementing a newly designed single-chip structure, as well as a new semiconductor package.

By utilizing this module in various devices, NEDO and Mitsubishi Electric expect to contribute to the expanded usage of smaller and more energy-efficient power electronics equipment for high-voltage railcars and electric power systems.
