ABB launches silicon carbide-based railway chargers

ABB, a global leader in power and automation technology, will unveil a new product at this week's Berlin trade fair – silicon carbide-based semiconductor devices that can be widely used in a new generation of battery chargers
on all railways.

The new compact battery charger complements ABB's large stand-alone auxiliary converter product range and is compatible
with battery voltage standards for all trains.

This SiC semiconductor technology applied to traditional silicon-based devices has significant advantages in reducing losses
at high switching frequencies and high temperatures.
At the same time, the technology can significantly reduce the size, weight and cooling requirements of chargers, while also improving system efficiency and better serving
rail operators.

Modern trains have different requirements for electronic components, and components for short-distance trains should be as lightweight as possible to improve the energy efficiency of the entire system; Long-distance and high-speed train components require compact, powerful and reliable equipment
.
High-speed trains on the Swiss Federal Railways (SBB) connecting Zurich and Milan will be equipped with this new ABB
.
