These traction units from Ingeteam will bring significant advantages to trains in terms of efficiency, dimensions, and weight. The roof-mounted, liquid-cooled traction converters feature an integrated auxiliary inverter and are designed to fit the train, ensuring more sustainable transport in every project. They are configured as an intelligent integration of extensively tested Power Modules. Furthermore, special attention has been paid to achieving high efficiency, the necessary redundancy, and easy maintenance to help ensure safe operation.

The traction converter allows electrical power from the 25kV, 50Hz AC overhead line (Serbian version) and 15kV, 16 2/3 Hz AC overhead line and battery (German version) to be converted into the voltage and frequency required to power the motors and other energy needs of the train.
Specifically, the converters for Serbia will be roof-mounted, liquid-cooled, and include two 525kVA active-front rectifiers, two 500kVA motor inverters (on-wheel), and one 115kVA auxiliary inverter. The converters for Germany are also roof-mounted, liquid-cooled, and include two 700kVA DCL-Ink converters, two 450kVA motor inverters (on-wheel), four 550kVA DC/DC converters for the ESS (Electrical Stability System), and two 85kVA auxiliary inverters.

The design of the converters will take place at Ingeteam's headquarters in Zamudio (Bizkaia) over the coming months. Following this, the verification and validation process will be carried out in Ingeteam's power electronics laboratory, one of the most advanced in the world. Finally, the manufacturing process will be managed from the Ortuella plant, which opened at the end of 2019 and is currently operating at full capacity. These new contracts add to the list of railway sector agreements signed for the plant in the last year.
