摘要

双向DC/DC变换器中大功率储能电感的设计是一个难点。为了克服这一困难，本文对双向DC/DC变换器的交错磁积分理论进行了研究。其中，4相Buck+Boost双向DC/DC变换器中所有4相电感均与两个2相耦合电感交错磁集成。深入研究了交错磁集成双向DC/DC变换器稳态相电流纹波和Buck模式下瞬态相电流响应速度，给出了双向DC/DC变换器的设计准则。最后，用仿真和实验结果对理论进行了验证。

A comprehensive analysis of coupled inductors in 4 phases interleaving bidirectional DC/DC converter

It is a difficult work to design a large power energy storage inductor in bidirectional DC/DC converter. In order to overcome this difficulty, this paper studied the interleaving magnetic integration theory of bidirectional DC/DC converter. In which all the 4-phase inductors in 4-phase Buck+Boost bidirectional DC/DC converter were interleaving magnetic integrated with two 2-phase coupled inductors. The steady state phase current ripple and transient phase current response speed in Buck mode of the interleaving magnetic integrated bidirectional DC/DC converter were studied deeply, and the design criterion of the bidirectional DC/DC converter was given. Finally, the theory was verified with simulation and experimental results.
