摘　　要：给出一种从输出滤波电感的电流波动系数KRP 出发 ,设计开关电源输出滤波电感的新方法 .解决了目前一直沿用的传统的设计方法中依靠经验设计、缺乏完善的理论设计依据的不足 ,给出了严格的输出滤波电感设计方法和电感上电流有效值及输出滤波电容上电流纹波有效值的计算公式 。By introducing current ripple ratio K RP , this paper shows a novel method for designing the output inductor of switching power supply. This method solves the shortage of method often used today. The traditional method is based on the designer's experience and has not enough design ground. This paper gives out a strict way to design output inductor and root mean square of the current in the output inductor as well as capacitor, which provides reliable design data for output inductor.
