World’s First SiC Power Modules, made with SiC Transistors and SiC Diodes

Mitsubishi Electric SiC Power ModuleMitsubishi Electric has announced the development of railcar traction inverter with all-SiC (Silicon Carbide) power modules made with SiC transistors and SiC diodes. The new inverter is expected to significantly reduce power loss (by 30%), size as well as weight (by 30% to 65%) of equipment used in high power trains (including Japan’s Shinkansen) in comparison to conventional insulated gate bipolar transistor (IGBT) power modules and hybrid power modules made with Si Transistors and SiC diodes.
The new traction inverter system’s switching loss is roughly 55% less than Mitsubishi Electric’s conventional inverter system incorporating IGBT power modules. Furthermore, the new system increases regenerated energy through the use of regenerative brakes in all speed ranges.
