摘　　要：利用Simplis/Simtrix软件搭建典型的敏感设备计算机电源模型,仿真和分析计算机电源对电压暂降的免疫度,并绘制计算机电源的电压暂降免疫度曲线.仿真分析结果表明:电压暂降幅值不同,维持计算机电源持续运行时间也不同,暂降幅值越小,运行时间越短;滤波电容有利于提升电压暂降免疫度,电容越大,供电电压整流波形和输出电压波形更为平稳,电压暂降免疫度曲线的工作区间范围也更大.A typical model of computer power supply source for sensitivity evaluation is built by u- sing Simplis/Simtrix software, and the immunity degree of voltage sag for computer power supply source is analyzed in this paper. The immunity degree curve for computer power supply source is thus drawn. Results show that the continuous running time of keeping computer power supply source is varying from the amplitude of voltage sag, the running time is shorter while the amplitude is smaller;and the filter capacitance can improve the immunity degree, the waveform of rectifier power supply voltage and the output voltage are more stable with larger adopting filter capacitance, and the working range of immunity degree curve of voltage sag is also larger.
