ABB Railway: Smaller, lighter,<br />
more energy-efficient<br />
The power electronics used in this new type of traction transformer<br />
from this exhibitor make it smaller and lighter than other, conventional<br />
models, as well as improving the efficiency of the train. The new<br />
PETT (power electronic traction transformer) is based on an innovative<br />
multilevel inverter topology, which uses high performance IGBT<br />
(insulated gate bipolar transistor) semiconductors and mid-frequency<br />
transformers. These replace the conventional combination of transformer<br />
and rectifier. The mid-frequency transformer also reduces<br />
noise levels. As part of a long term partnership between Swiss Railways<br />
(SBB) and ABB a PETT pilot installation is currently being tested<br />
in a shunting locomotive. This is based at the main station in Geneva<br />
and is powered both by a 15 kV AC and 1.5 kV DC supply. The<br />
PETT currently being deployed has a rated output of 1.2 MW and can<br />
produce up to 1.8 MW over short periods.<br />

ACKSYS: WIFI SOLUTION FOR RAILWAYS<br />
At <strong>InnoTrans</strong> 2012, French manufacturer ACKSYS introduces its new<br />
and extremely robust wireless product: « WLn-ABOARD ». The technology<br />
of this innovative WiFi device has been specifically tailored<br />
for railway applications. It features all the proven technologies of the<br />
“WLg-ABOARD” and offers above all a dual radio IEEE 802.11n a/b/g<br />
(up to 2 x 300 Mbps). This dual RF design is the outstanding attribute<br />
of the entire solution, allowing the WLn-ABOARD to operate simultaneously<br />
two separate networks for carriage bridging and in-carriage<br />
communication and to provide a secure and highly available<br />
wireless connection. WLn-ABOARD enables operators to improve<br />
mobile communications in motion (thanks to its optimized roaming<br />
performances: handover = 0 ms) and to develop a wide range of new<br />
in-vehicle networking applications such as wireless Internet access,<br />
Voice over IP, passenger WiFi services, CCTV and smart vehicle<br />
diagnostic/maintenance.<br />
