摘要
在电路分析中经常会遇到一些阻尼振荡电路,由于这类电路在高压断路器开断能力测试、受控热核研究等许多重要的工程领域有着极为广泛的应用,因此有必要对此类电路的特性加以讨论研究。通过介绍建立数学模型的方法,对利用时域中传统的微分方程法和频域中经典的拉普拉斯变换法对电路进行了分析。最后借助于MATLAB软件对RLC电路的过渡过程进行了仿真的分析,并对其产生的误差作出了一定的解释。
The damped oscillation circuit tends to emerge in circuit analysis. Due to its wide application in various leading engineering fields, it is necessary to discuss about the characteristics of this category of circuit. In light of introduction of the method to set up mathematical modeling, the article takes up analysis on circuit using time domain differential equation method and frequency domain Laplace transform method（LTM） In the end, the author takes up simulation analysis on the transition process of RLC circuit with the help of MATLAB and accounts for the difference.
