| Research Abstract |
In the case of charging the battery(Lithium-ion battery) of the electric vehicle, it is necessary to decrease the current ripple included in charging current. Though the current ripple can be decreased by using the mass electrolytic capacitor, the cost and the volume of the battery charger is raised. In this research, a high-frequency AC link DC-DC converter is used as the battery charger and new control scheme is proposed for this DC-DC converter. The effect of the decrease of the capacity of the electrolytic capacitor by using the proposal method is described.
