Efficient Traction and Auxiliary Converters
Traction SiC
o Energy saving : - 10% @ train level (Regional train)
o Operator should implement in tenders energy criteria with a high weight and a dedicated cost model
Medium Frequency Architecture
o Automatic reversible mode to supply (HVAC & Traction) from auxiliary batteries (ie: can move train in depot without catenary)
o IGBT or Full SiC technology , Naturally Cooled or by air forced
o Up to 30% less volume and weight. Efficiency (full power) : 96%
Optimized Traction Converter & Cooling Systems
o Optimized converter PWM & control strategy limiting inverter & traction motor losses and maximizing the regeneration in brake
o Move from forced air to natural cooling (fan removed)
o Maintenance gain for the operator
