| 摘 要： | 为确定开关电源元件参数，对Buck型开关稳压电源电路具体工作原理和各部分功能进行详细分析，并建立实时仿真模型。根据所建立的数学模型，利用电路分析软件PSpice进行瞬态特性分析，得到开关电源输出电压和电感电流的瞬态响应特性；对滤波电容的等效串联电阻（ESR）进行参数分析，分析了电容退化对输出纹渡电压的影响，为开关电源的故障诊断与故障预测提供了新的思路。

| Abstract: | To determine the parameters of switching-mode power component,the working principle and the functions part of Buck switching-mode power supply circuit are analyzed,and its real-time simulation model is built.On the basis of mathematical model,a transient analysis is made with PSpice,which can gain the transient response of output voltage and inductance current.A parametric analysis for equivalent series resistor(ESR) of filter capacitor is made,and then the effect of capacitor degradation on ripple voltage ... |
