摘要
开展用于储能系统的双向DC/DC的研究,分析Buck/Boost-DAB级联系统的拓扑结构,给出了级联系统的协同控制策略,实现了级联系统的宽范围电压输入,解决了DAB变换器在输入、输出电压不匹配时的功率回流问题,提高了系统的效率。该控制方案实现了Buck/Boost变换器和DAB变换器的特性互补,同时实现电气隔离和宽电压输入范围。
In this thesis,the bidirectional DC/DC converter for energy storage system is studied.Then the topology Buck/Boost-DAB are analyzed and the cooperative control strategy is proposed,and the wide-range voltage input of system is realized.Meanwhile,the cooperative control strategy of cascade system solved the power backflow problem of DAB converter when the input and output voltages are not matched and improves the efficiency of the system.This control scheme realizes the complementary characteristics of Buck/Boost converter and DAB converter,while realizing electrical isolation and wide voltage input range.
