AMELIORATION DES EMISSIONS DE COURANT HARMONIQUE D'UN CHARGEUR DE BATTERIES INTEGRE AUX VEHICULES ELECTRIQUES

HAL (Le Centre pour la Communication Scientifique Directe) (2016)

Christelle Saber Denis Labrousse Bertrand Revol Alain Gascher

Ce travail concerne l'etude d'un chargeur de batteries pour les vehicules electriques. La topologie est constituee d'un redresseur triphase commande abaisseur de tension unidirectionnel en courant suivi d'un hacheur elevateur de tension (type Boost). Ces types de redresseur injectent sur le reseau des harmoniques HF de courant dus a la commutation des semi-conducteurs qui sont attenues par un filtre d'entree de mode differentiel. L'energie reactive des condensateurs de filtrage conduit a un courant reseau en avance de phase par rapport a la tension. Afin d'obtenir un facteur de deplacement unitaire, une loi de commande qui agit directement sur le dephasage du courant en entree du redresseur est mise en oeuvre. Cette loi de commande associee a la topologie du chargeur excite periodiquement l'un des modes propres du filtre d'entree et degrade ainsi la qualite du courant absorbe au reseau. Afin de limiter cet effet, un amortissement actif base sur l'emulation d'une resistance virtuelle est propose. Il permet d'obtenir un bon facteur de puissance tout en repondant aux exigences des normes internationales sur les emissions de courants harmoniques.

A review of on-board integrated chargers for electric vehicles

Nadim Sakr Daniel Sadarnac Alain Gascher

Electric vehicles (EVs) use grid power to charge their batteries. Because the battery is charged only when the car is parked -except for regeneration at braking-, using the on-board traction system components to form an integrated charging device is made possible. This paper presents a review of on-board integrated EV chargers and design criteria. It is aimed at presenting a state of the art on the integrated chargers to researchers, designers, and engineers. A classified list of around 70 research articles is also appended for a quick reference.

A combined switched reluctance motor drive and battery charger for electric vehicles

Nadim Sakr Alejandro Fernandez Sanchez Daniel Sadarnac Alain Gascher

In this paper, a new multi-purpose switched reluctance machine drive with charging capabilities is introduced. This topology satisfies propulsion requirements and allows single phase as well as three-phase AC charging. In charging mode, the machine windings are used as inductors and the zero torque condition is maintained by canceling out all tangential forces. Every component of the SRM drive is used during charging and no additional components are needed. The proposed topology is theoretically analyzed, and its validity is verified by simulation software.

A combined CM & DM conducted EMI modeling approach: Application to a non-isolated on-board single-phase charger for electric vehicles

2022 International Symposium on Electromagnetic Compatibility – EMC Europe (2017)

Christelle Saber Denis Labrousse Bertrand Revol Alain Gascher

This paper presents a specific conducted electromagnetic interference (EMI) model for power electronics converters combining both common mode and differential mode emissions. This model allows the estimation of the conducted emissions solely based on the semi-conductors' switching functions. It offers the possibility to chain models in order to emulate the conducted EMI behavior of a global power electronics conversion system. The approach is applied to a non-isolated on-board single-phase charger for electric vehicles. Simulations using Psim software are carried. Future works consist in the experimental validation of the proposed method along with the determination of the frequency range of validity.

Power Line Communication Implementation in Electrical Architecture

SAE technical papers on CD-ROM/SAE technical paper series (2003)

Anne Laliron Olivier Maurice Alain Gascher

The implementation of the new electronic equipment makes the electrical and electronic architecture more and more complex. Thus technologies such as Power Line Communication constitute alternative solutions to reduce the number of wires and optimize the harness. Taking into account the know how and applications for household use, the power line communication feasibility in automotive domain had to be performed. This paper deals with the essential parameters to be identified in order to provide the appropriate power line modulation. Harness EMC behavior and EMI disturbances inside vehicle are developed in this paper.

Challenges Facing PFC of a Single-Phase On-Board Charger for Electric Vehicles Based on a Current Source Active Rectifier Input Stage

IEEE Transactions on Power Electronics (2015)

Christelle Saber Denis Labrousse Bertrand Revol Alain Gascher

This paper aims to study the power factor (PF) correction scheme for a single-phase on-board charger of electric vehicles. The topology is based on a unidirectional current source active rectifier (CSAR) consisting of four insulated-gate bipolar transistors in series with four diodes followed by a boost converter. Buck-type rectifiers inject low-order input current harmonics into the ac mains. Thus, an inductor–capacitor ( LC ) input filter is employed. The capacitor's reactive energy results in a leading grid current. In order to achieve a unity displacement power factor, a phase shift control is implemented. However, the LC filter is prone to series and parallel resonances coming from the grid disturbances and the converter harmonics, respectively. Therefore, the phase shift control strategy combined with the topology of the CSAR results in a periodical resonance of the input filter. This phenomenon is studied in detail. In order to reduce the grid current's distortion level, an active damping control with resonance frequency tracking that achieves a good PF while meeting the IEC's international standards on harmonic current emissions is presented. An experimental test bench is developed to validate the simulations’ theoretical findings. Compliance with the standards is achieved and system limitations are discussed.
