  2. 1. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles

    Author : Erik Nordlund; Chandur Sadarangani; Hans Kahlen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electrical Machines; Hybrid Vehicles; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. READ MORE

  5. 3. Dynamic analysis of a novel electromagnetic transducer for hybrid vehicle and experimental verification

    Author : Sylvain Chatelet; Chandur Sadarangani; Jorma Luomi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Machines and Drives; Electrical engineering; Elektroteknik;

    Abstract : This thesis presents the results of the work carried out on the dynamic analysis and experimental performance measurements of a novel concept of electromagnetic system for hybrid vehicle powertrains. The main focus of this work is to present how this novel electromagnetic system can be operated in a hybrid vehicle and to show how a prototype of this system has succesfully been operated in a laboratory set-up.
