【摘要】Interleaving technique is widely used in high power and multiple DC-DC converters,and effectively decreases the ripple value of DCDC converter and improves the power supply quality.The paper is mainly on the basis of the character of interleaving technique,the quantitative relationship between the peak-to-peak amplitude with duty cycle and the triggering pulse phase shift under the condition of the ripple superposition of the input and output current of multiple DC-DC converters.The conclusion can be applied to non-isolated DC-DC converters in different topological structure.At last,under the MATLAB/SimuIink environment,the simulation result of paralleled DC-DC converter interleaving with three modules proves the correctness of the conclusion,and has certain significance for the reduction of the ripple amplitude in paralleled DC-DC converters.%交错并联技术在大功率、多重化DC-DC变换器应用广泛,能够有效地减小DC-DC变换器的纹波值从而提高其供电品质.根据交错并联技术的特点,通过对DC-DC变换器输入、输出电流的纹波波形进行叠加分析,推导出在多模块并联条件下,纹波峰峰值与占空比和各模块触发脉冲相移之间的定量关系.推广到不同拓扑结构的非隔离DC-DC变
