Inverter Drive System Stability for Traction Applications
2005 IEEE Vehicle Power and Propulsion Conference, 2005The inverter drive system stability is a classical problem but not understood widely and fully by the industry. Especially for railway traction applications with substations and network distributed parameters also taken into consideration, the question becomes very complicated and so far, there is no satisfactory analytical method or model to cover the

Gaining Traction: Thermal Management and Reliability of Automotive Electric Traction-Drive Systems
IEEE Electrification Magazine, 2014Increasing the number of electric-drive vehicles (EDVs) on America?s roads has been identified by the U.S. Department of Energy (DOE), the federal cross-agency electric vehicle (EV)-Everywhere Challenge, and the automotive industry as a strategy with near-term potential for dramatically decreasing the nation?s dependence on oil.

International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2006. SPEEDAM 2006., 2006
The state-of-the-art drive system of today's metro or commuter trains with underfloor traction equipment consists of a 3-phase IGBT inverter, feeding two or four induction traction motors in parallel. For torque transmission from the traction motor to the wheelset, a gear unit is required for the drive.

Dynamic behavior of a trolley traction system with a flexible driving rope
2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS), 2015The rope traction driven trolleys are widely used in modern port machineries especially on the quayside cranes since it has so many benefits compared with a self-driving system. However, the system is more complex for automatic control since: (1) the system has different mass distribution varies according to different load cases; (2) the rope's ...

EMC filters in high voltage traction drive systems
2008 International Symposium on Electromagnetic Compatibility - EMC Europe, 2008Recent and future traction concepts for vehicles comprise electric drives. The traction system with its topology implemented within the vehicle has to be considered as an electromagnetic interference (EMI) source with different coupling paths. EMC concepts have to be defined to limit the EMI levels to tolerable limits as required by existing EMC ...

CLAMPING SYSTEM FOR A TRACTION MECHANISM DRIVE
2003The invention relates to a clamping system (1) for a pre-tensing mechanism drive (35) wherein it is possible to obtain an automatic preliminary voltage of the traction mechanism (3). The clamping system (1) comprises a work eccentric (5) which can be rotate in a limited manner between two stops (26, 27) in relation to a base plate (8).

A segmented traction drive system with a small dc bus capacitor
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012The standard voltage source inverter (VSI), widely used in electric vehicle/hybrid electric vehicle (EV/HEV) traction drives, requires a bulky dc bus capacitor, typically made of polypropylene films, to absorb the large ripple currents generated by the pulse width modulated switching actions and prevent them from damaging and shortening the battery's ...

Oscillatory processes in a nonlinear system of an individual traction electric drive
Truck, 2023When the tires interact with the road in contact, self-oscillations occur. The appearance of self-oscillations in the interaction zone can serve as a useful diagnostic sign of the development of the process of loss of adhesion in the work, cases of self-oscillations for an individual electric drive are investigated.
