摘要
针对传统蓄电池组充电方式中充电电压和充电电流中存在较大的纹波,采用二重积分间接滑模控制提高双向DC/DC变换器的稳定性与鲁棒性及动态性能,降低输出电压中的纹波。为了更好地抑制双向DC/DC变换器输出电流中的纹波,改善传统LC滤波器的不足,采用LCL滤波器抑制纹波电流。最后搭建试验样机,验证了理论的正确性。
In the traditional battery charging mode,there are larger ripples of charging voltage and current. The double integral indirect sliding mode control was adopted to improve the stability,robustness,dynamic performance of the bidirectional DC-DC converter,then the output voltage ripple is reduced. In order to suppress the bidirectional DC-DC converter output current ripple and improve the deficiency of the traditional LC filter,an LCL type filter was proposed to restrain the current ripple. An experimental prototype was built to verify the correctness of the theory.
