Siemens Mobility has entered Memorandum of Understanding (MoR) with Mitsubishi Electric Europe on the use of high-voltage silicon carbide (SiC) technology to improve the energy efficiency of rail propulsion systems.

The companies will work in the field of SiC power module technology to support sustainable transport as well as save electricity in the transport sector.

The EU has pledged to achieve climate neutrality by 2050 with the European Green Treaty. It aims to eliminate net greenhouse gas emissions by 2050.

In the interim phase, emissions are expected to be reduced by 55% by 2030 compared to 1990.

Siemens said that “the European Green Deal will lead to sector-specific directives on CO” emissions.

The railway industry and its suppliers, as well as the technologies and components used in railway transport, are expected to play a key role in achieving the sustainable goal.

Power semiconductors are said to play a crucial role in railway vehicles, ranging from trams to high-speed trains.

The continuous development of standard silicon-based power semiconductors and the advancement of new technologies such as SiC will help improve efficiency and reduce carbon emissions.

Mitsubishi Electric is said to be setting new technology standards with SiC technology and decarbonizing Siemens Mobility’s railways.

Mitsubishi Electric’s SiC devices are used in applications such as traction inverters on trains. Its full SiC 3300 V power supply modules facilitate energy savings and reduce traction inverters.

The appropriate SiC chipset for high-speed switching will be deployed in the standardized LV100 package to provide low scattered inductance and easy parallelism capability.

Using battery-powered Mireo Plus technology, Siemens can electrify railways even without a continuous overhead contact line.

Siemens added: “SiC technology is particularly useful for regional trains with innovative battery-powered hybrid propulsion for use in railway sections with or without overhead contact line.
