为适应新一代低压、大电流和快速暂态响应的功率需求,提出一种“UUUU”形耦合电感结构,通过分析揣合电感的磁通分布,建立了磁路模型,从而得出自感、漏感和互感的计算公式,给出耦合电感的设计方法。通过仿真和实验证明,证明了磁件模型的正确性,得出“UUUU”形耦合电感器具有加工工简单,电感量大,磁通密度分布更均匀、直流叠加特性好等优点。用于交错并联磁集成双向DC/DC变换器,具有相电流纹波小,
An "UUUU" shape coupled inductor structure is proposed, a magnetic circuit model, this paper gives the design method. The simulations and experiments show that, "eye" type coupled inductor has the advantages of simple processing, the advantages of large inductance, magnetic flux density are more uniform, DC superposition characteristic etc.. For interleaved hi-directional DC/DC converter with magnetic integration, with the current ripple is small, high efficiency
