  1. 11. Analysing hybrid drive system topologies

    Författare :Karin Jonasson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. LÄS MER

  3. 12. Design Aspects of Inductive Power Transfer Systems for Electric Vehicle Charging

    Författare :Daniel Pehrman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stray field measurements; shielding; electric vehicle charging; inductive power transfer; full-bridge resonant inverter; finite element method FEM ; series-parallel compensation; coupled inductors; series-series compensation; silicon carbide;

    Sammanfattning : During the last decade the transition towards electric propelled vehicles has had an upswing and electric vehicle (EV) sales has increased steadily. This is much due to legislations on lowering emissions but also due to lower total cost of ownership. LÄS MER

  4. 13. Studies on Current Commutation in Hybrid DC-breakers

    Författare :Jesper Magnusson; Göran Engdahl; Magne Runde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commutation; Hybrid DC-breakers; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Compared to conventional AC-circuit breakers, a DC-breaker has to act fast and force the current down to zero. Many different DC-breaker topologies are available, and this thesis is focused on the hybrid DC-breaker comprising a mechanical switch and high power semiconductors. LÄS MER

  5. 14. Analysis and control of a hybrid vehicle powered by free-piston energy converter

    Författare :Jörgen Hansson; Mats Leksell; Chandur Sadarangani; Anders Malmquist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-piston energy converter; FPEC; series hybrid electric vehicle; SHEV; power management; energy management; powertrain evaluation; equivalent consumption minimisation; ECMS; linear engine; Electrical engineering; Elektroteknik;

    Sammanfattning : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. LÄS MER

  7. 15. Simulation and Design of a Radial-Radial Four-Quadrant Transducer for Hybrid Electric Vehicles

    Författare :Erik Nordlund; KTH; []
    Nyckelord :Electrical Machines; Hybrid Vehicles;

    Sammanfattning : This report is my licentiate thesis at the Royal Instituteof Technology, (KTH) in Stockholm. The work was done at thedepartment of Electrical Engineering, division of ElectricalMachines and Power Electronic.An internal combustion engine (ICE) in a conventionalvehicle operates rarely at optimum efficiency.
