摘　　要：为满足工程应用需要,本文通过讨论RLC二阶串联电路在欠阻尼状态下的零输入响应,深入分析了R,L,C三者之间的关系,并根据所需的电压、电流值及反峰电压推导和归纳出了计算电路中R,L,C参数的公式。经Multisim软件仿真,误差小于2%。公式推导条理清晰,使用方便。To meet the needs of engineering applications,this paper analyzed the relationships among R,L and C by discussing the zero-input response of RLC second-order series circuit in the state of underdamping.Furthermore,according to the required voltage and current values,a series of formula to calculate the circuit R,L,C parameters were derived and summarized.Through the Multisim simulation,it is proved that the error is less than 2%.These formulas are easy to use and the course of deduction is clear.
