2. Integrated Compact Drives for Electric and Hybrid Electric Vehicles
Abstract : To develop more competitive solutions, one of the trends in the development of drive systems for electric and hybrid electric vehicles (EVs/HEVs) is to integrate the power electronic converter and the electric motor. This thesis aims to investigate the performance and the operation of modular converters in integrated motor drive systems for EVs/HEVs. READ MORE

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