| Abstract |
In the 3kVDC catenary countries where the operator is concerned about its old designed rolling stock
(camshaft system or thyristor chopper feeding DC motors), a 3kV IGBT Chopper can be proposed to
replace the electrical propulsion system.
Up to now, the 3kV IGBT chopper could be designed with 3.3 kV or 4.5 kV IGBT used in 3-level
schemes (e.g. : imbricated cells) or in 2-levels schemes (e.g. : direct serial connection with active
clamping).
The coming of the 6.5 kV IGBT permits to design 2-levels converters directly connected to the
3kVDC catenary with no need of serial connection.
This paper presents the development of a chopper based on the 6.5kV IGBT module. |
