Abstract :
This paper presents a topology of an on-board charger with direct grid connection for battery electrical vehicle in which the system components are adapted and optimized by integrating the electrical machine and the voltage source inverter of the traction drive into the charging strategy. The particular safety issues concerning the impact of the common mode voltage in the charging operation are pointed out and its solution of integrating a filter capacitor between the protection earth conductor and the neutral conductor is described. A system simulation model including the electrical components and the control strategy is discussed. An integrated loss calculation of the power electronic components in the simulation model enables the analysis of the efficiency of the introduced on-board charger. Based on the simulation results a design of the electrical machine and the filter capacity can be performed to discuss the packaging issues of the concept introduced.
