摘要为了克服传统EE形耦合电感器的气隙过于集中、磁压和磁通分布不均匀、气隙离绕组过近等缺点,提出一种“E王E”形耦合电感器结构,建立了磁路模型,给出了设计方法。通过仿真和实验证明,该结构增加了一条并联气隙磁路从而使磁路的磁压和磁通分布比较均匀,磁路的磁阻减小,电感因数和耦合强度增大;气隙远离绕组从而减小气隙扩散磁通和旁路磁通及绕组涡流损耗;绕组绕在长宽比较小的铁心中柱上从而减小绕组长度;所给出的改进磁路模型和设计方法可以用于这种耦合电感器的设计;将这种耦合电感器用于交错并联磁集成双向DC-DC变换器,具有输出电压纹波小、电感电流波形平滑、毛刺少、开关管开通和关断时的电流尖峰小等优点,并且可以有效地提高电路的轻载效率。

Abstract：In order to overcome the disadvantages of traditional EE coupled inductor’s that the distributions of the air gaps were too concentrated, the distributions of the magnetic pressure and flux were not uniform, and the air gaps were too nearly to the windings, this paper proposes a structure of “E 王 E” shape coupled inductors and sets up its magnetic models and gives the design method. It is proved that in the “E 王 E” structure, a parallel connection air gap magnetic circuit is increased to make the distributions of the magnetic pressure and flux more uniform, the reluctance smaller, the inductance and strength of coupling larger, and the air gaps are far away from the windings to reduce the air gaps’ diffusion flux and bypass flux and eddy current loss. The windings are wrapped around the central poles which has smaller length-width ratio to reduce the wingding’s length. The magnetic models and the design method could be used to design the “E 王 E” shape coupled inductors. When the “E 王 E” shape coupled inductors are used to interleaving magnetic integration bidirectional DC-DC converter, the ripple wave of the output voltage is smaller, the wave form of the inductor current is smoother, and the peak current is smaller when the switch are turned on and turned off, meanwhile the efficiency of circuit light load is greatly improved.
