中文摘要：
通过对交错并联Boost变换器（IBC）的不连续导电模式（DCM）及其电感电流和输入电流纹波进行理论分析,推导出了输入电流纹波与上升和下降斜率、占空比、电感电流连续时间和变换器周期时间的比值关系表达式.提出在特定电压增益条件下,优化电感能够使输入电流纹波减小到零.通过Matlab仿真和实验验证了理论分析的正确性.
英文摘要：
The discontinuous conduction mode （DCM）,inductor current and input current ripple of interleaved Boost converter（IBC） is analyzed theoretically.Based on the detailed analysis,numerical formula of input current ripple about rising and falling slope,duty ratio and the ratio of inductance continuous time and the period time are deduced.It points that under the specific voltage gain,optimized inductance can reduce input current ripple to zero.Matlab simulation and experiment results are in positive to the theoretical analysis results.
