摘　　要：设计了一种适用于激光器脉冲驱动系统的低纹波交错并联boost变换器,采用多路交错并联结构有效降低了系统重载下的输出电压纹波,理论空载最大输出电压120 V,最大输出功率119.2 W,重载下电压纹波低于5 mV。分析了交错并联Boost变换器的并联路数和每路电感放电时间间隔等参数对输出电压纹波的影响,并提出利用单路Boost变换器输出参数估算多路电压纹波的方法,可为交错并联Boost变换器并联路数的确定提供依据。A low voltage ripple interleaved parallel Boost converter for a pulsed laser driver is designed,and a multi-channel interleaved parallel structure is adopted to effectively reduce the output voltage ripple under heavy load.The theoretical no-load maximum output voltage is 120 V,the maximum output power is 119.2 W,and the output voltage ripple under heavy load is less than 5 mV.The effects of the number of parallel channels and the time interval of each channel inductance discharge on the output voltage ripple are studied in detail.In addition,the method for estimating the ripple of multi-channel output voltage based on the output parameters of a single-channel Boost converter is summarized,which can provide a basis for determining the number of parallel channels of the interleaved parallel Boost converter.
