  7. Abstract:
  8. Constantly rising fuel prices and environmental consciousness have caused alternative transport solutions to be considered.Recently, batteries and electric vehicle industries have developed to become a reasonable alternative for gasoline powered cars. Plug-In hybrid electric vehicles could be connected to the electrical grid to be recharged. To ease the charging process, one solution could use an on-board charger to charge the electric vehicle. This charger should be able to be connected to a conventional outlet for convenience reasons and moreover, it should be a grid friendly charger in order not to pollute the electrical network. After studying the introduced structures for electric vehicle battery chargers and the related issues, four new integrated plug-in hybrid electric vehicle battery chargers have been proposed in this thesis. The four proposed structures, benefiting the Dual Bridge Series Resonant Converter, are isolated and the semiconductor devices could be switched in ZVS and ZCS conditions, in addition to having bidirectional power flow capability.It should be noted that the proposed chargers are integrated and no external hardware is added to the traction mode electric system. Finally, modeling and analysis of the proposed battery chargers have been presented and their performance has been investigated in PSIM software environment
