| 摘 要： | 为了满足越来越大的储能系统规模对大功率储能变流器的需求，将多重化DC/DC变换器引入储能变流器的拓扑结构。对多重化DC/DC变换器的电流纹波及谐波特性的分析表明其具有显著优势。储能变流器的控制策略加入基于直流母线电压的下垂控制。对所研究的储能变流器拓扑结构及控制策略进行仿真并搭建样机。仿真和实验结果表明，所设计的基于多重化DC/DC变换器储能变流器性能具备大功率充放电的功能并且性能优良。

| Abstract: | In order to meet the demand of power conversion system with the increasing scale of high-power energy storage system, the interleaved DC/DC converter is used in the topology of high power conversion system. It is found that the interleaved DC/DC converter has a significant advantage in the current ripple and harmonic by analyzing the characteristic of the DC/DC converter. The droop control is added to the control strategy of the power conversion system. The simulation model and experimental prototype about the topology and control strategy of power conversion system are built. The results demonstrate the proposed converter has large power charge/discharge function with good performance. |
