[1] Control Strategies for Open-End Winding Drives Operating in the Flux-Weakening Region IEEE Transactions on Power Electronics, Vol. 29, N°. 9, pages. 13, 09/2014, Abstract SANDULESCU Alexandru-Paul, MEINGUET Fabien, KESTELYN Xavier, SEMAIL Eric, BRUYERE Antoine |
This paper presents and compares control strategies for three-phase open-end winding drives operating in the flux-weakening region. A six-leg inverter with a single dc-link is associated with the machine in order to use a single energy source. With this topology, the zero-sequence circuit has to be considered since the zero-sequence current can circulate in the windings. Therefore, conventional over-modulation strategies are not appropriate when the machine enters in the flux-weakening region. A few solutions dealing with the zero-sequence circuit have been proposed in literature. They use a modified space vector modulation or a conventional modulation with additional voltage limitations. The paper describes the aforementioned strategies and then a new strategy is proposed. This new strategy takes into account the magnitudes and phase angles of the voltage harmonic components. This yields better voltage utilization in the dq frame. Furthermore, inverter saturation is avoided in the zero-sequence frame and therefore zero-sequence current control is maintained. Three methods are implemented on a test bed composed of a three-phase permanent-magnet synchronous machine, a six-leg inverter and a hybrid DSP/FPGA controller. Experimental results are presented and compared for all strategies. A performance analysis is conducted as regards the region of operation and the machine parameters. |
[2] Flux-weakening operation of open-end winding drive integrating a cost effective high-power charger IET - Electrical Systems in Transportation, Vol. 3, N°. 1, pages. 10 - 21, 03/2013, URL, Abstract SANDULESCU Alexandru-Paul, MEINGUET Fabien, KESTELYN Xavier, SEMAIL Eric, BRUYERE Antoine |
In this study, a three-phase drive with a six-leg voltage source inverter and an open-end winding interior permanent magnet synchronous machine designed for traction of an electric vehicle is studied in a ﬂux-weakening operation. The topology allows the functionality of a high-power charger to be obtained, without adding any other supplementary power devices. On the other hand, since there are three independent currents, the control structure has to handle not only the two dq-current components but also a zero-sequence current. If neglected, in comparison with a wye-coupled three-phase drive, this zero-sequence component can cause a higher maximum peak value of the phase currents, additional stator Joule losses, torque ripple, inverter voltage saturation and insulated gate bipolar transistor (IGBT) oversizing. The proposed control strategy consists in adapting a conventional method used for wye-connected machines particularly in ﬂux-weakening operation. This strategy allows the closed-loop control of the zero-sequence current to be maintained in the whole speed range and therefore inverter saturation is avoided. Simulations and experimental results are presented and analysed. |

This communication deals with a comparison between two methods of discretisation: the well known Finite Element Method and the Natural Element Method that is a meshless method. An error estimator, based on the non-verification of the constitutive law, is used. This estimation has been applied to two examples: a device with permanent magnets and a variable reluctance machine. |

For Electric Vehicles (EV), the charger is one of the
main technical and economical weaknesses. This paper focuses on
an original electric drive [1]-[3] dedicated to the vehicle traction
and configurable as a battery charger without need of additional
components. This cheap solution can outfit either electric or
plug-in hybrid automotive vehicles, without needing additional
mass and volume dedicated to the charger. Moreover, it allows a
high charging power, for short duration charge cycles. However,
this solution needs specific cares concerning the electrical
machine control. This paper deals with the control of this drive
[1], focusing on traction mode. In introduction, a review is done
about topologies of combined on-board chargers. Then, the
studied topology is introduced; using a 3-phase brushless
machine supplied with a 6-leg Voltage Source Inverter (VSI). A
model for its control is defined in the generalized Concordia
frame, considering the traction mode. Then, an analysis of this
model is established using a multimachine theory and a graphical
formalism (the Energetic Macroscopic Representation denoted
EMR). Using EMR, a description of energy flows shows specific
control constraints. Indeed, numerical simulations illustrate the
perturbations on the currents and the torque when controlling
the machine with standard control methodologies. An improved
control, deduced from the previous analysis, shows good
performances, strongly reducing currents and torque ripples.

[4] Identification of a 7-phase claw-pole starter-alternator
for a micro-hybrid automotive application
International Conference on Electrical Machines (ICEM08), 09/2008, Abstract BRUYERE Antoine, HENNERON Thomas, LOCMENT Fabrice, SEMAIL Eric, BOUSCAYROL Alain |
This paper deals with the identification of a new high power starter-alternator system, using both: a Finite Element Method (FEM) modeling and an elementary experimental vector control. The drive is composed of a synchronous 7-phase claw-pole machine supplied with a low voltage / high current Voltage Source Inverter (VSI). This structure needs specific approaches to plan its electrical and mechanical behaviors and to identify the parameters needed for control purpose. At first, a Finite Element Method (FEM) modeling of the machine is presented. It is used for the predetermination of the electromotive forces and of the torque. Experimental results are in good accordance with numerical results. In a second part, resistive and inductive parameters of the drive are determined by an original experimental approach that takes into account each component of the drive: the battery, the VSI and the machine. |
[5] Modeling and Control of a 7-phase Claw-pole Starter-alternator
for a Micro-hybrid Automotive Application
IEEE-VPPC’08, Harbin (China), 09/2008, Abstract BRUYERE Antoine, SEMAIL Eric, BOUSCAYROL Alain, LOCMENT Fabrice, DUBUS Jean-Marc |
This paper deals with the modeling and the control of a new high power 12V starter-alternator system. The drive is composed of a 7-phase synchronous claw-pole machine with separate excitation, supplied with a 7-leg Voltage Source Inverter (VSI) designed for low voltage and high current. The system is modeled in a generalized Concordia frame and a graphical description is used to highlight energetic properties of such a complex system. A control scheme is then deduced from this graphical description. Two controls are achieved in generator mode: one is using the VSI in a square-wave mode, the other in a Pulse Width Modulation (PWM) mode. Experimental results are provided. |
[6] Identification of sensitive R-L parameters of a multiphase drive by a vector control IEEE Power Electronics Specialists Conference (PESC08), 06/2008, Abstract BRUYERE Antoine, SEMAIL Eric, LOCMENT Fabrice, BOUSCAYROL Alain, DUBUS Jean-Marc |
This paper focuses on an experimental method to determine the electric parameters of a seven-phase low-voltage multiphase drive. The drive is a belt driven starter-alternator for powerful cars with Hybrid Electrical Vehicles (HEV) functions. The resistive and inductive parameters are necessary to obtain the six characteristic time constants of the control modeling. Classical direct measurements lead to imprecise results because of very low values for the windings electric resistance and inductance. Effects of the imprecision on the measurements are all the more important that time constants are obtained by a ratio of cyclic inductances by resistance, with cyclic inductances being a linear combination of seven measured inductances. The methodology for identification detailed in this paper is based on a stator current vector control, in a multi-reference frame. This methodology allows us to get directly these time constants. Numerous measurements allow the robustness of the method to be evaluated. |
[7] Teaching drive control using Energetic Macroscopic Representation - initiation level EPE’07, 09/2007, Abstract BOUSCAYROL Alain, BRUYERE Antoine, DELARUE Philippe, LEMAIRE-SEMAIL Betty, GIRAUD Frédéric |
The Energetic Macroscopic Representation (EMR) has been developed in 2000 to develop control of systems with several drives. Since 2002 this graphical tool has been introduced to teach drive control in France, then Canada and Switzerland. The University of Lille proposes two drive control units for students in electrical engineering: initiation level and expert level unit. This first paper deals with the content of the initiation level unit and describes the simulation project of an electrical vehicle using EMR. |

[9] Comparison of 3-, 5- and 7-leg Voltage Source Inverters for low voltage applications IEMDC 2007, 05/2007, Abstract LOCMENT Fabrice, BRUYERE Antoine, SEMAIL Eric, KESTELYN Xavier, BOUSCAYROL Alain |
In the context of high power low-voltage
applications as starter-generator for automotive, multi-phase
drives present the attractive characteristic of reducing the
current per phase and per leg. A 5- or 7-phase machine is also
more suitable for using concentrated windings, attractive for
their short end-windings and subsequently for a higher
expected torque-to-volume density. In this perspective, the 5-
and 7-leg Voltage Source Inverters (VSI) are compared with the
3-leg VSI. In the first part, for the same set of resistances and
inductances coupled in different wye-coupling configurations,
we examined the DC-bus currents and the power recovered by
the load for a square-wave VSI control: the 7-leg VSI is the
more efficient because it makes best use of the harmonics. In the
second part, the torque ripples of 3-, 5- and 7-phase drives are
compared: the 7-phase drive torque ripples are the lowest ones
because of the less sensitivity to the harmonics of the currents.
In the last part, a Pulse Width Modulation control is studied,
with almost the same voltage harmonics amount as this one
obtained with the square-wave mode control. Experimental
results are given for the 7-leg VSI either with a passive load or
with a 7-phase permanent magnet synchronous motor. |
