[6] 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, URL, 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. |
[7] 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. |

[1] Automotive Charger Grid-Forming Control Opportunities for G2V and V2X Applications 2023 IEEE Vehicle Power and Propulsion Conference (VPPC), 01/2024, URL, Abstract FAYAD Elie, SAL Y ROSAS Damian, BRUYERE Antoine |
Given the widespread use of electric vehicles, they can be used in their idle state to provide services when connected to the grid or supply power in islanded operation using the bidirectional charger. Today, when connected to the grid, reversible chargers employ grid-following control, and when operating in islanded conditions, they use constant voltage constant frequency control. However, limitations exist for both control strategies. In this context, grid-forming control can be used to operate in all cases. This paper showcases the potential of grid-forming control when applied to a reversible charger for different operation modes of electric vehicles. |
[2] Virtual Power-Based Technique for Enhancing the Large Voltage Disturbance Stability of HV Grid-Forming Converters 2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe), 09/2023, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
Grid-forming control plays an essential role in the modernization of HV electrical transmission grids, particularly in mitigating challenges imposed by large voltage disturbances. In this context, the concept of virtual power has gained prominence as a potential approach that improves stability following such disturbances. This paper illustrates the use of virtual power method in enhancing the large disturbance stability given by the grid-forming control. An adaptive virtual impedance is also proposed to further improve system dynamics. The methods are evaluated through large disturbance stability analysis and time-domain simulations. |
[3] Impact of Grid-forming Converter on Electromechanical Oscillations Conférence, 06/2023, URL, Abstract BOUKHENFOUF Johan, GUILLAUD Xavier, BRUYERE Antoine |
As distributed generation increases, it is essential to study its impact on the grid dynamics. This paper focuses on understanding the influence of the emergent technology of Grid-Forming converters on the electromechanical oscillations of the power system. Interactions among synchronous generators and gridforming converters are analyzed thanks to simplified models. These highlight the similarities of both sources, and thus, explain the participation of the converter in the oscillation. They also revealed the differences that justify the damping effect of Grid-Forming converter. This conclusion, obtained with simplified models, is validated with a small-signal stability analysis of a detailed model in the dq0-frame |
[4] Impact of aluminum casing on high-frequency transformer leakage inductance and AC resistance EPE 2022 ECCE Europe: 5 – 9 September 2022, Hannover, GERMANY, 09/2022, Abstract BAKRI Reda, MARGUERON Xavier, DA CUNHA ALVES Wendell, CIMETIERE Xavier, GILLON Frédéric, BRUYERE Antoine, VATAMANU Lucian |
High-Frequency (HF) transformer is a central part of isolated HF power converters. Its parameters, in particular leakage inductance and losses, have a significant impact on the overall converter performances. With the increase of switching frequencies linked to the use of SiC and GaN based active devices, the control of the HF transformer parameters becomes essential. A HF transformer is usually designed without considering its surrounding. However, the latter can have a significant impact on the transformer's performance. In this paper, the effect of an aluminum casing surrounding the transformer is studied and quantified for two parameters: The transformer leakage inductance and the supplementary losses. The goal is to consider the casing effect in the early design stage of power converters. |
[5] PQ Decoupling on Grid-Forming Converter Connected to a Distribution Network 2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 06/2022, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
In recent years, several works on grid-forming converters in transmission networks have been performed. Since these high voltage grids are mainly inductive, a natural decoupling exists between active and reactive power controls. This decoupling facilitates the design and the performance of the grid-forming controllers. However, in distribution applications, it is well known that the R/X ratio of the line impedance is substantially higher, preventing the system from a natural decoupling effect. This paper proposes an original solution to decouple the control and gives an application to a low voltage connection of a grid-forming converter. |
[6] Operating Grid-Forming Control on Automotive Reversible Battery Charger 2021 IEEE Vehicle Power and Propulsion Conference (VPPC), pages. 6, 10/2021, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
Nowadays, the production of electric energy is evolving towards decentralized systems by an increasingly advanced integration of new active loads such as electric vehicles and renewable energy sources. This energy transition involves the use of power electronics converters to regulate energy exchanges. In this context, this paper brings the L2EP knowledge on grid-forming control developed in a high-voltage context to the ValeoSiemens reversible charger. This comprises two significant differences in the sizing of the system: a lower grid connection impedance and a resistive aspect of the distribution network. To overcome these challenges, this paper proposes two techniques: the virtual impedance to compensate the low value of connection impedance and dynamic decoupling of active and reactive power to consider the resistive effect of the distribution network. |
[7] Impact of grid-forming control on the internal energy of a modular multi-level converter EPE2020, 09/2020, Abstract ZHANG Haibo, ROKROK Ebrahim, QORIA Taoufik, BRUYERE Antoine, FRANCOIS Bruno, BELHAOUANE Moez, GUILLAUD Xavier |
This paper presents a comparative analysis of the dynamic behavior of a Modular Multi-level Converter (MMC) with grid-forming control either with or without controlling the MMC internal energy. It has been demonstrated that the internal energy of the MMC in low-level control interacts with the high-level control, which is performed by a grid-forming scheme. In case of controlling the internal energy of the MMC, this interaction is mitigated. Moreover, it has been shown that the dynamic behavior of a grid-forming controlled MMC with internal energy control is identical to an equivalent 2-level Voltage Source Converter (VSC). |

[9] Effect of Using PLL-Based Grid-Forming Control on Active Power Dynamics Under Various SCR IECON'2019-IEEE, 10/2019, Abstract ROKROK Ebrahim, QORIA Taoufik, BRUYERE Antoine, FRANCOIS Bruno, GUILLAUD Xavier |
This paper investigates the effect of using phaselocked loop (PLL) on the performance of a grid-forming
controlled converter. Usually, a grid-forming controlled
converter operates without dedicated PLL. It is shown that in
this case, the active power dominant dynamics are highly
dependent to the grid short circuit ratio (SCR). In case of using
PLL, the obtained results illustrate that the SCR has a negligible
effect on the dynamic behavior of the system. Moreover, the
power converter will not participate to the frequency regulation
anymore; therefore, the converter response time can be adjusted
independently to the choice of the droop control gain, which is
not possible without PLL. A simple equivalent model is
presented which gives a physical explanation of these features. |

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.

[16] 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. |
[17] Modeling and Control of a 7-phase Claw-pole Starter-alternator
for a Micro-hybrid Automotive Application
IEEE-VPPC08, 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. |
[18] 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. |
[19] Teaching drive control using Energetic Macroscopic Representation - initiation level EPE07, 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. |

[21] 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. |
