| 摘 要： | 本文首次提出运用线性函数和组合波形原理，推导开关电源任意N通道交错并联拓扑输出电流纹波幅值与单通道占空比关系的数学模型，根据数学模型可以定量表达任意N通道交错并联拓扑输出电流纹波幅值大小，为设计具有最优输出电流纹波特性的交错并联拓扑奠定了理论基础。

| Abstract: | The principle of linear functions and combined wave forms is first presented. The principle is used to derive a mathematical model of relations between the current ripple amplitude using interleaving-parallel topology in arbitrary N channels and the duty cycle of single channel. The current ripple amplitude using the interleaving-parallel topology in N channels can be quantitatively expressed by the mathematical model. A theoretical foundation is determined for designing a optimal current ripple characteristics by interleaving-parallel topology. |
