| Abstract |
Low frequency, medium voltage transformers in main line rail vehicles suffer from poor efficiency
and high weight. Completely transformerless solutions were not up to now attractive due to the high
motor and converter expenditures. To solve these problems, motors with a more medium voltage
friendly winding structure as e.g. an induction motor with fractional slot winding are proposed. Based
on the new 6.5kV IGBT, the feasibility of multilevel converter topologies as the diode clamped
converter and the flying capacitor converter is analysed. The paper gives an evaluation of drive
concepts combining motor and converter properties. A solution with 4 series connected drives turns
out to be the most favourable solution. |
