A Combined Model Flux Observer for Vector Control of Traction Asynchronous Motors

2007 7th International Conference on Power Electronics and Drive Systems, 2007
Vector control induction motor drives are particularly sensitive to the variation of motor parameters. As a consequence, the field orientation is missed, leading to substantial degradation of performance. The performance of traction motors can be even more degraded by the substantial core loss due to their high supply frequency.

CONTROL OF A CURRENT INVERTER-FED ASYNCHRONOUS MACHINE FOR RAILWAY TRACTION AND ALTERNATIVE MOTORS IN GENERAL

IFAC Proceedings Volumes, 1983
Abstract Torque of AC motors fed by current source inverter is suitably controlled by regulation of the torque angle of the motor which provides very good stability and performances without the need of a speed or position feed-back. A very simple circuit is presented to perform this control strategy with good efficiency.

Study of a test system for asynchronous traction motors using sinusoidal current

Известия высших учебных заведений. Электромеханика
This study investigates methods to reduce output voltage harmonics in autonomous voltage source inverters (VSI) uti-lized in high-speed trains by comparing two modulation techniques: Space Vector Pulse Width Modulation (SV-PWM) and Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM).

Investigation of work of asynchronous traction motors powered by the d. c. catenary

2012
Unified structure of the converter on the basis of high frequency transformers is proposed by author, which provides the ability to work of multi-system locomotive at the various parameters of contact net and various types of traction motors. The converter includes several functional units of energy conversion, which requires maximizing the energy ...
