摘要：

在多相VRM中采用磁集成技术可以提高VRM的响应速度，本文提出了利用多副磁芯统一集成的多相耦合阵列式集成磁件结构，并以应用于四相非隔离交错并联型VRM中的四相耦合阵列式集成磁件结构为例进行了分析。分析了VRM降低稳态纹波及提高动态响应与集成磁件耦合度的关系；分析了耦合磁芯磁轭磁阻对集成磁件参数的影响，并进行了仿真验证，对比了集成磁件参数不对称对VRM性能的影响。给出了集成磁件的设计方法，样机实验结果验证了理论分析和仿真结果的正确性。

Abstract:

Applying electromagnetic integration technology in heterogeneity VRM could improve the response speed of VRM, proposing to use many vice core unified integrated multiphase coupling array type integrated magnetic structure in this paper, taking the four-phase non-isolation interleaved VRM’s four-phase coupling array type integrated magnetic structure for example to analysis. Analyzed the relationship between VRM reduce the steady state ripple as well as enhance the dynamic response with the integrated magnetic coupling degree. Analyzed and simulation verified the influence of coupling magnetic core’s yoke resistance to integrated magnetic parameters, comparing to the influence of integrated magnetic parameters asymmetry to VRM’s performance. Giving the design method of integrated magnetic, through prototype experimental demonstrate the validity of the theoretical analysis and simulation result.
