In this paper, an attempt has been made to investigate analytically the dynamic performance of selfcommutating current source inverter-fed induction motor drive with volts/Hz control strategy. Speed and current PI regulators are used in realization of closed loop control structure of the drive system. The closed loop mathematical modeling of the complete drive system is presented in the synchro...

Asymmetrical six-phase induction machines are widely used in high-power safety-critical applications. The so-called pseudo winding layout has recently been proposed as a promising contender for high power medium voltage applications terms of torque density, phase current quality, simple single-layer-based stator design, and fault-tolerant capability. This employs quadruple three-phase sets conn...

Abstract In the Wendelstein 7-X (W7-X) stellarator, vacuum rotational transform, ? , has a flat radial profile and does not cross any major rational resonance. Nevertheless, during plasma operation ?profile can be strongly modified by electron cyclotron current drive in such way that resulting -profile passes through low-order values, this trigger magnetohydrodynamic (MHD) events. Indeed, W7-X ...
