摘　　要：研究了一种可应用于光储系统中的非隔离型三端口变换器,通过调节3个开关管来实现不同工作模式的平滑切换,分析了不同工作模式运行的能量流动状态,改变传统PI调节固定参数调节的思路,提出了一种非固定的PI参数调节方法,通过对比实验,实现了超调量的减小和调节速度的加快。通过分析拓扑结构在不同工作模式下的运行状态,研究其功率流动管理的控制策略,并结合仿真实验,验证其理论的可行性和有效性。A non-isolated three-port converter that can be applied to the optical storage system was studied, which realized the smooth switching of different working modes by adjusting three switch tubes, analyzed the energy flow state of operation in different working modes, changed the idea of tradi-tional PI adjustment fixed parameter adjustment, proposed a non-fixed PI parameter adjustment method, and realized the reduction of overshoot and the acceleration of adjustment speed through comparative experiments. By analyzing the operating status of the topology in different working modes, the control strategy of power flow management is studied, and the feasibility and effective-ness of the theory are verified by combining simulation experiments.
