INGETEAM HAS DEVELOPED AND VALIDATED A NEW TRACTION CHAIN FOR HIGH POWER, BASED ON 3-LEVEL TOPOLOGY THAT HAS BEEN PROVED AT THE GROUP´S FACILTIES, INCLUDING A SIMULATION OF REAL OPERATION ON A HIGH SPEED MULTI-VOLTAGE (25 KV /3 KV /1.5 KV ) SYSTEM.
The results of tests showed that this traction system will deliver a higher energy efficiency; comparing to the classic systems based on bi-level technology, the efficiency will be around 30% higher.
The combined tests have allowed an optimization of all the elements, including the control system. Validation includes the accomplishment of all requirements, including noise levels, thermic characterization and the route simulation. All this process will help to reduce the mounting period and the vehicle testing.
The investment done by INGETEAM on those facilities amounted 3 Mio Euro. Furthermore, validation of traction system has been going through several months, involving a multi-disciplinary team.
