Control and operation of open-end winding permanent magnet synchronous wind generator

2017 Brazilian Power Electronics Conference (COBEP), 2017
This work presents a wind energy conversion system with an open-end winding permanent magnet synchronous generator. Two 2-level back-to-back converters with independent DC-links are used to connect the system to the grid. The grid and the inverter are connected via a three windings transformer and an inductive filter. The modulation used on the machine

Overvoltage mitigation in open-end winding AC motor drives

2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015
An over-voltage mitigation technique for open-end winding electrical drives with long power cables is proposed in this paper. In particular, a suitable dwell time is included in the switching patterns of the two inverters to minimize the over-voltage occurring at the stator terminals of this kind of systems.

Circulating currents in open-end winding PWM ac drives

IECON 2010 - 36th Annual Conference on IEEE Industrial Electronics Society, 2010
Circulating currents have been experimentally observed in pulse-width modulated ac open-end winding drives. These currents have the effect of increasing conduction losses in the stator winding resistance of the ac machine. Two major causes for these currents have been identified as device voltage drops in power semi-conductor devices and dead-time used
