摘　　要：本文提出的"I王I"形耦合电感器通过增加磁路气隙的数量,使磁路的磁压分布更加均匀,与传统铁心电感器相比显著减小了磁路的电磁损耗、电磁干扰和线圈的涡流损耗,且增大了窗口面积。通过分析耦合电感器的磁通分布,建立磁路模型,给出了耦合电感器的设计方法,并对所提出的耦合电感器进行仿真,结合双向DC/DC变换器的实验验证了"I王I"形耦合电感器结构的可行性。In this paper, the proposed ‘I王I＇ coupled inductor overcomes the disadvantages of existing energy storage inductor＇ s complex structure, such as bigger magnetic pass loss, and nonuniform distribution of magnetic pressure, and makes magnetic pressure distribution more uniform by increasing the quantity of magnetic circuit＇ s air gap. Compared with traditional ＇ EE＇ and ＇ EI＇ core inductors, ‘I王I＇ significantly decreases the electromag- netic loss of magnetic circuit, electromagnetic interference and eddy current loss of coil, as well as reduces the height of coil structure effectively which can increase the field angle of magnetic circuit and improve magnetic circuit structure, and also increases the window area. Through the analysis of coupled inductor flux distribution, the paper establishes magnetic circuit model and provides the design method of coupled inductor, then verifies the feasibility of the ‘I王I＇ coupled inductor structure through simulation and experiment of bidirectional DC/DC converter.
