Presentation

Innovative inverter topology boosting drivetrain efficiency to new levels.

Inverter based on silicium carbid (SiC) semiconductors seem to be the mainstream for efficient electric drivetrains when it comes to the automotive car industry. However, there are hurdles to introduce this technology in the working machine sector. ABB’s new innovative 3-Level topology inverter allows an even smoother and more energy efficient operation of any type of electric motors which reduces cost of ownership (Best Efficiency Control). The presentation will give an overview on challenges and solutions to improve the drivetrain efficiency for working machines followed by efficiency comparison on real life duty cycles.
