| Abstract |
This paper proposes a new method for the current ripple reduction of a three-phase interleaved bidirectional DC?DC converter. Usually, the three-phase interleaved bidirectional DC?DC converter is used for battery charging and discharging to reduce battery current ripple. In V2G application, a PWM AC?DC converter is used to connect the AC power grid and three-phase interleaved bidirectional DC?DC converter for battery charging and discharging. The magnitude of DC link voltage affects the battery current ripple magnitude. Therefore, the magnitude of the battery ripple current is analyzed with variations of battery and DC link voltages. The ripple current magnitude is found to be minimized by controlling the DC link voltage. Simulation and experimental results show the usefulness of the proposed method. |
