摘要
从能量观点出发,揭示一阶电路暂态过程产生的原因;对于一阶电路的三要素,重点分析储能元件初始状态和稳态的等价电路;深入讨论时间常数的性质。理解和掌握一阶电路三要素是熟练运用三要素法的基础。
Firstly,as viewed from energy,the reason why the first-order circuit must go with a transition is exposed.Secondly,equal circuit of inductance and capacitance is analyzed when the circuit is being switched and has switched for a long time.The property of time constant is discussed thoroughly.Finally,the steps of three-elements method are demonstrated with an example.
