| 中文摘要: |
| 电动汽车用动力蓄电池组对充电电流纹波极其敏感,但是其本身具有反电动势,内阻极小,容易使充电器输出的充电电流纹波过大。针对以上问题,从滤波器抑制电流纹波的算法,快速响应能力以及输出的可调范围三个方面,对电动汽车充电器的直流滤波器的设计方法进行了讨论并通过仿真验证了设计方案的合理性和可行性。 |
| 英文摘要: |
| The power accumulator battery in the electric automobile is extremely sensitive to the charging current ripple.But itself has tiny inner resistance and opposing electromotive force,little charge/discharge voltage fluctuation will cause large charge current ripple.This paper discussed the DC/DC filter design method of the electric automobile charger based on three aspects:restraining the charging current ripple,increasing the response speed and variable range of output.Simulations proved that the filter desi... |
