7. 5. Energy Efficiency Comparison Between Two-level and Multilevel Inverters for Electric Vehicle Applications

   Författare :Oskar Josefsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicle EV ; Drive Cycle; Plug-in Electric Vehicle PEV ; Multilevel Inverter MLI ; Two-level Inverter TLI ; Efficiency.; Integrated Charger;

   Sammanfattning : In order to contribute to the development of energy and cost efficient electric vehicles, a thorough analysis of two different electric converter topologies is performed, considering different drive cycles and different control strategies. In the electric vehicles available on the market today, a high voltage (200−400 V ) battery pack composed of several battery modules is connected to one or more inverters which create AC voltages to the electric propulsion machines.
