Proceedings of the Institution of Electrical Engineers, 1975
A d.c. traction drive is described comprising a synchronous motor, which may be brushless, supplied by a forcecommutated voltage-source invertor with thyristor firing controlled by rotor position. This implies control of load angle. An analytical basis for system design is presented, and the required ranges of variation of load angle to obtain motoring

Inverters [traction propulsion drives]
IET 13th Professional Development Course on Electric Traction Systems, 2014Traction propulsion inverter drives, particularly the VSI, are expected to continue to be the most popular option for the foreseeable future. Technical advances in semiconductor switching devices and advanced microprocessor based controllers have contributed significantly to making such drives economic and reliable.

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">It is time to introduce a new component to motorsports engineering - the driver. SAE papers rarely deal with the cognitive control system which fills the space between the steering wheel and the seat. It seems that only the safety papers admit the presence of a driver, and they treat the driver as a passive object ...

5th IET Professional Development Course on Railway Electrification Infrastructure and Systems (REIS 2011), 2009
This paper presents an overview of railway traction systems. Railway vehicles are characterised by low rolling resistance, and high inertia, therefore the traction drives must have suitable capabilities to deliver the required vehicle performance. Both AC and DC motors are in common use in the railway sector, but have very different power delivery ...
