    • Error Estimators for Proper Generalized Decomposition in Time-Dependent Electromagnetic Field Problems 
      Article dans une revue avec comité de lecture
      MULLER, F.; HENNERON, Thomas; HAMEYER, K.; ccCLENET, Stephane (Institute of Electrical and Electronics Engineers, 2020)
      Due to fine discretization in space and time, the simulation of transient electromagnetic phenomena results in a large system of equations. To cope with this computational effort, model order reduction techniques can be ...
    • 3-D Multi-Nodal Thermal Modelling for Fault-Tolerant Machine 
      Communication avec acte
      OUENZERFI, Safouene; ZAHR, Hussein; TRABELSI, Mohamed; BOUBAKER, Riadh; HARMAND, Souad; ccSEMAIL, Eric (IEEE, 2019)
      Even if intrinsically a five-phase machine can work with one opened phase, thermal constraints (temperatures in windings and Permanent Magnets) impose to decrease the mean torque in faulty operation mode. In order to ...
    • Demagnetization analysis of an open-end windings 5-phase PMSM under transistor short-circuit fault 
      Communication avec acte
      DOS SANTOS MORAES, Tiago José; NGUYEN, Ngac Ky; ccSEMAIL, Eric (IEEE, 2019)
      For an open-end windings integrated Permanent Magnet Synchronous Machine, the demagnetization of the permanent magnets is analyzed when a transistor is short-circuited and no specific control strategy is adopted. Depending ...
    • A novel Sensorless Control Strategy Based on Sliding Mode Observer for Non-Sinusoidal Seven-phase PMSM 
      Communication avec acte
      MINI, Youssouf; NGUYEN, Ngac Ky; ccSEMAIL, Eric (2020)
      This paper proposes a new sensorless control strategy based on a Sliding Mode Observer (SMO) for a non-sinusoidal seven phase PMSMs. This strategy, based on all harmonics contained in the back-EMF, is compared to the ...
    • Design of a bi-harmonic 7-phase PM machine with tooth-concentrated winding 
      Article dans une revue avec comité de lecture
      BECKER, Florent; ZAHR, Hussein; ccSEMAIL, Eric; ccSCUILLER, Franck (Institute of Electrical and Electronics Engineers, 2020)
      If multi-phase machines equipped with tooth concentrated winding with half a slot per pole and per phase offer interesting characteristics (simplified manufacturing, no space subharmonic, fault-tolerant ability), their low ...
    • Direct AC Voltage Control for Grid-Forming Inverters 
      Article dans une revue avec comité de lecture
      QORAI, Taoufik; LI, Chuanyue; OUE, Ko; COLAS, Frédéric; GUILLAUD, Xavier; ccGRUSON, Francois (2019)
      Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., ...
    • Critical clearing time determination and enhancement of grid-forming converters embedding virtual impedance as current limitation algorithm 
      Article dans une revue avec comité de lecture
      QORIA, Taoufik; COLAS, Frédéric; DENIS, Guillaume; PREVOST, Thibault; GUILLAUD, Xavier; ccGRUSON, Francois (Institute of Electrical and Electronics Engineers, 2019)
      The present paper deals with the post-fault synchronization of a voltage source converter based on the droop control. In case of large disturbances on the grid, the current is limited via current limitation algorithms such ...
