  • Abstract Recently, the development of electric vehicles (EVs) is valued, and the battery charger is the core of the development of EVs. Therefore, a requirement of the bidirectional power converter is increased. In the thesis, a three-phase dual-active-bridge bidirectional DC converter with a pack of 48V/20AH LiFePO4 batteries is developed to implement a charging/discharging EV battery system. To improve efficiency of the converter, a hybrid modulation is proposed and used to boost efficiency under the light-load condition. A charging/discharging strategy of battery is planned by analysis of the modulation, and validate effectiveness of the strategy was verified from experimeantal results. Finally, the LabVIEW graphical software and CAN-bus protocol are used to produce the current command, which is sent into a digital signal process (DSP) to realize the control of the converter.
