An open-end winding drive with a single DC voltage source
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015In this paper, a novel multiphase multilevel open-end winding (OeW) drive is presented. The topology employs one three-level and one two-level voltage source inverter (VSI) to supply a five-phase OeW machine. Three-level VSI operates with low switching frequency, while the second inverter is used to mitigate unwanted low-order harmonics. Proposed drive

Control and operation of open-end winding permanent magnet synchronous wind generator
2017 Brazilian Power Electronics Conference (COBEP), 2017This 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

High bandwidth current control for open-end winding induction motor
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014In this paper, high bandwidth current control for an open-end winding induction motor is realized with deadbeat control. A deadbeat current controller achieves higher gain than a PI current controller by compensating for the error caused by the digital sampling delay.

2015 4th International Conference on Systems and Control (ICSC), 2015
This study proposes a comparative analysis between the performances of the star windings and open-end stator windings of the synchronous machines with wound rotor without damper windings. The advantages of the open-end stator windings at the level of the THD voltage and the torque undulation are presented It is shown that the novel dual open-end stator

Grid-Connected Open-end Winding Induction Motor Drives
2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2020An open winding approach can lead to substantial performance improvement on grid-connected induction motors, which are still largely used for constant speed applications. Exploiting an open-end winding configuration to manage bidirectional power flows, the proposed configuration is less expensive than a conventional variable frequency induction motor ...

An Open-end Winding approach to the design of multi-level multi-motor drives
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016An Open-end Winding approach to the design of multi-motor drives exploiting multi-level inverters is presented in this paper. A key feature of the proposed approach is that a single multi-level inverter is tasked to provide the entire active power required by the system, while a two-level inverter acts as a power filter, providing a zero average active

Overvoltage mitigation in open-end winding AC motor drives
2015 International Conference on Renewable Energy Research and Applications (ICRERA), 2015An 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, 2010Circulating 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

A Grid Connected Open-End Winding Induction Generator System With Series Compensation
IEEE Transactions on Industry Applications, 2020This paper presents a new grid connected induction generator system having open-end stator windings with a series compensator (voltage source inverter (VSI) connected in series) for reactive power compensation. The proposed scheme consists of a two-level capacitor fed voltage source inverter connected to one side of the windings of the induction ...

Synchronous modulation of cascaded inverters of asymmetrical open-end winding motor drive
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Algorithms of space-vector-based synchronized pulsewidth modulation (PWM) have been applied for control of dual-inverter fed open-end winding induction motor drive supplied by two isolated dc-sources with non-equal voltages. It has been shown, that algorithms of synchronized PWM provide continuous phase voltage symmetry for any ratios (integral or ...
