  2. 1. Quasi Resonant DC Link Converters - Analysis and Design for a battery Charger Application

    Author : Per Karlsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quasi resonant DC link converter; soft switching; converter efficiency; IGBT; battery charger;

    Abstract : Environmental aspects have during the last years made electric vehicles an interesting competitor to the present internal combustion engine driven vehicles. For a broad introduction of pure electric vehicles, a battery charging infrastructure is deemed necessary. However, to build and maintain such an infrastructure is costly. READ MORE

  4. 2. An Isolated Integrated Charger for Electric or Plug-in Hybrid Vehicles

    Author : Saeid Haghbin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galvanic Isolation; Grid Synchronization; Vehicle Applications; Integrated Battery Charger;

    Abstract : For electric and hybrid vehicles using grid power to charge the battery, traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger.In this Licentiate thesis, an isolated high power integrated charger is proposed, designed and constructed based on a special ac machine with a double set of stator windings called motor/generator.

  5. 3. Integrated Motor Drives and Battery Chargers for Electric or Plug-in Hybrid Electric Vehicles

    Author : Saeid Haghbin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum torque per Ampere strategy.; integrated motor drive and battery chargers; field-oriented control; battery charger; isolated and non-isolated integrated charges; Plug-in vehicles; split-phase PM motor;

    Abstract : Plug-in vehicles, electric vehicles or plug-in hybrid electric vehicles, use grid power to charge the battery. The components in the traction circuit, like the electric motor and the inverter, are not used during the battery charging, so there is a possibility to use them in the charger circuit to reduce the size, weight and price of the on-board charger; that is called an integrated motor drive and battery charger or simply an integrated charger which can be galvanically isolated or non-isolated from the utility grid.

  6. 4. Analysis and Control Aspects of a PMSynRel Drive in a Hybrid Electric Vehicle Application

    Author : Shuang Zhao; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active damping control; electric drive; electric vehicle; hybrid electric vehicle; integrated charger; permanent-magnet assisted synchronous reluctance machine; position estimation; sensorless control;

    Abstract : This thesis deals withmodeling and control of an electric drive equipped with a permanentmagnet assisted synchronous reluctance (PMSynRel) machine for a plug-in hybrid electric vehicle application.In the first part of the thesis, a special use of the PMSynRel machine in consideration, known as an integrated charger concept, is investigated.

  7. 5. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

    Author : Shuang Zhao; Chandur Sadarangani; Sigurd Övrebö; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

    Abstract : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. READ MORE
