摘　　要：为提高双频DC-DC变换器的功率密度,提出一种将独立的高低频电感集成在一个EIE型磁芯上的磁集成电感器设计方案,通过建立集成磁件的电路-磁路等效模型,设计了双频DC-DC变换器的EIE型磁集成电感器的结构,建立了集成电感的等效模型,对磁集成双频DC-DC变换器进行了仿真分析,并通过实验平台验证了新型磁件的运行效果。结果表明:新型磁件设计合理,可以在系统中稳定运行,通过测量得到集成磁元件的体积和质量分别为原来的27.6%和23.3%,使得双频变换器系统的功率密度得到了提升。In order to improve the power density of the double-frequency DC-DC converter,a design scheme of a magnetic integrated inductor that integrates high frequency inductors and low frequency inductors in an EIE-type magnetic core was designed.By establishing the circuit-magnetic circuit equivalent model of the integrated magnetics,the structure of the EIE magnetic integrated inductor of the double-frequency DC-DC converter was designed,the equivalent model of the integrated inductance was established,and the magnetic integrated double-frequency DC-DC converter was simulated and analyzed.The rationality of the new magnetic component was verified.The results show that the experimental platform verifies that can work stably in the system.The volume and mass of the integrated magnetic component are measured to be 27.6%and 23.3%of the original,respectively,which improves the power density of the double-frequency converter system.
