| Abstract |
A one-year experimentation in revenue service of a new concept of inverter is presented.
This experimentation has been performed on the underground line N°1 of the RATP between
“Château de Vincennes” and “La Défense”, one of the most frequented lines in Paris.
For this experimentation, an asynchronous traction drive has been modified using a two level voltage
inverter based on new concepts. The main principles supporting these new concepts will be described.
They have led to three types of innovation, which have been applied during the design: 1) Thermal integration: Direct water cooling on IGBT base plate
2) Electrical integration: Direct connection IGBTs / capacitors
3) Functional integration: inverter & cooling system in one removable sub-assembly. A data acquisition system have allowed us to follow this experimentation and provide data on the
main physical parameters (water temperature, air speed,…). An analysis of these data will be
proposed. |
