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 ...

Dual matrix converters based seven-phase open-end winding drive
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014This paper presents a novel seven-phase open-end winding drive system supplied by the dual non-square matrix converter. The input to each of the matrix converter is three phase utility grid system and the output is seven phase voltages with variable voltage and frequency. The two matrix converters feeding the seven-phase open-end load are supplied from

Multiphase Open-End Winding Induction Machine Drive With the Floating Capacitor
IEEE Transactions on Industry Applications, 2020A comprehensive control scheme is presented for the multiphase open-end winding induction machine drive topology, where the main inverter (MI) and floating inverter (FI) are supplied by a dc power source and a capacitor, respectively. Under the proposed method, the MI can work with the unity power factor, while the FI provides all the reactive power ...

Open-End Winding Triple Rectifier for Wind Turbine with Integrated Energy Storage
2025 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)An Open-End-Winding Boost Voltage Triple Rectifier is proposed as a simplified and efficient alternative for wind turbines integrating a battery pack. By incorporating six additional power diodes into a conventional three-phase diode rectifier, the system can triple the DC output voltage, enabling the use of standard 400V wind generators even at low ...
