Design and development of exclusive modulation techniques for effective power regulation in dual two-level-inverter-fed open-ended winding traction motors
… integral part of an EV propulsion system is the traction drive. The existing two-level inverter drives reportedly has several drawbacks. Multilevel inverter has been proposed as an improvement over the conventional inverter drive for EVs. Dual two-level inverter topology, fed from isolated DC …

Dynamic Braking Control for Accurate Train Braking Distance Estimation under Different Operating Conditions
… to control the amount of current through traction motors under various wheel/rail adhesion conditions while braking. Minimizing the braking distance of a train requires the dynamic braking forces to be maximized within the available wheel/rail adhesion. Excessively large dynamic braking …

A design framework for reconfigurable controllers with emphasis on electric drive wheels
Conventional controllers for traction motors used in electric and hybrid electric vehicles are presently designed to operate under fixed operating conditions, with a little or no flexibility in control over the hardware. The operator does not have the ability to control the performance in real time …

Finite element simulation based design and optimization of electric motors for EV/HEV traction application
… and optimization of permanent magnet based traction motors with given dimensions and drive constraints. The goal is to develop a method which has the accuracy of finite element method but with much smaller time consumption for designing and optimizing the motor. Since it is a traction motor, …

Electromechanical Suspension-based Energy Harvesting Systems for Railroad Applications
… locomotive generates electricity to power the traction motors and all the equipment required to operate the train, the electrical power cannot, in a practical manner, be carried out along the length of the train, leaving freight cars unpowered. While this has not been a major issue in the past, …
