摘　　要：应用多相交错并联耦合电感技术,可以有效降低相电流纹波、提升动态响应速度。针对不同设计目标,首先分析直接耦合电感和间接耦合电感的稳态性能和动态性能的影响因素;然后根据耦合前后等效动态电感不变设计提升稳态性能的直接耦合电感和间接耦合电感,根据耦合前后等效稳态电感不变设计提升动态性能的直接耦合电感和间接耦合电感;最后通过实验验证了理论分析的正确性和有效性。实验表明,2种不同耦合方式的耦合电感分别对提高变换器的稳态性能和动态性能有明显的效果。The application of multi-phase interleaved parallel coupled inductors technology can effectively reduce the phase current ripple and improve the dynamic response speed.Aimed at different design objectives,the influencing factors for the steady-state and dynamic performances of direct-and indirect-coupled inductors are analyzed.Subsequently,based on the invariant equivalent dynamic inductance before and after coupling,the direct-and indirect-coupled inductors are designed to enhance the steady-state performance.Similarly,based on the invariant equivalent steady-state inductance before and after coupling,direct-and indirect-coupled inductors are designed to improve the dynamic performance.Finally,the cor-rectness and effectiveness of the theoretical analysis were verified by experimental results,demonstrating that the two different coupling methods can significantly enhance the steady-state and dynamic performances of the converter,respectively.
