Siemens Mobility & Mitsubishi Electric Europe BV have signed a Memorandum of Understanding to cooperate in the field of SiC power module technology with the aim of enabling efficient and sustainable transportation and electrical energy savings in the transportation sector.Power semiconductors play a key role in railway vehicles, from trams to high-speed trains. Standard silicon-based power semiconductors are being continuously developed, and new technologies are being advanced, such as the use of SiC (silicon carbide), which will enable even greater efficiency and the greatest reduction in weight in future. It is in fact the railroad market that is stimulating demand for more efficient energy conversion technology.Mitsubishi Electric’s SiC devices have proven long-term reliability in the most demanding of applications such as traction inverters in trains. The potential for energy savings through the use of Mitsubishi Electric's wide range of SiC power devices in railway technology exists particularly in the area of traction drives. In particular the full SiC 3300 V power modules contribute to energy saving and the downsizing of traction inverters. The suitable SiC chipset for high-speed switching is used in the standardized LV100 package, which provides low stray inductance and easy paralleling capability. The power losses of LV100 full SiC modules can be reduced by approximately 75 % compared to the conventional Si power modules during the inverter operation. As a result, the efficiency of the traction inverter is increased.
