摘　　要：对RLC电路中的暂态响应进行了理论分析,介绍了负阻抗变换器组成的负电阻方波电源电路设计的原理及实现方法,用Multisim仿真了接入负电阻方波激励下的各种暂态响应,包括:非振荡、临界振荡、衰减振荡、等幅振荡、发散振荡。仿真结果与理论一致,且能够直观地描述RLC二阶串联电路各态响应,克服了实验设备的不足。The transient response of the second order RLCcircuit is theoretically analyzed.The design principle and implementation of the negative resistance square wave excitation with the negative impedance converter are introduced.Then five state responses are simulated by Multisim,including non-oscillating,critical oscillation,damped oscillation,the oscillation amplitude,and divergent oscillation.The simulation result is in accordance with the theoretical result.The various state responses of the RLCsecond order series circuit are directly described.And the shortage of laboratory equipment is effectively overcome.
