摘　　要：GLC电路是无源二阶电路主要结构之一,理论上多以RLC串联电路为主进行分析,而GLC电路理论分析的却很少,但由于GLC电路测试方便,而且其过阻尼状态、临界阻尼状态和欠阻尼状态3种状态过度平稳、波形易测等特点,在实验和实际应用中又非常的广泛。鉴于此,通过理论和对偶定律对GLC电路进行了分析,最后通过EDA软件对电路功能进行了仿真,采用了交互式仿真和图表仿真两种方式对电路的波形和状态轨迹波形进行了虚拟测试,仿真结果与理论分析结果相吻合,从而弥补了GLC电路在理论分析的缺失,对二阶电路的零输入响应、零状态响应和全响应有一个更深刻、全面的理解。GLC circuit is one of the main structure of the passive second order circuit,In theory,RLC series circuit is given priority to GLC circuit,but the GLC circuit is widely used in experiments and practical situation,because its overdamped state,critically damped state and under-damped state are excessive smoothly and waveform is easy to measure.In this article,first,the GLC circuit is analyzed through mathematics and duality theorem. Second,the GLC circuit functions are simulated by EDA software and by the interactive simulation and graph-based simulation. The simulation results coincide with the theoretical analysis,the conclusions make up the GLC theoretical analysis of second order circuit zero-input response and the zero-state response and a full response,thus,one can have a more profound and comprehensive understanding for the GLC.
