摘要
为更好地理解各功能电路的暂态过程和分析方法,加深对暂态过程电路的理解,在分析一阶RC电路暂态过程模拟基本原理的基础上,通过Multisim仿真软件模拟RC电路的暂态过程。根据电容是否能充满电或放完电的情况,对电路时间常数的测量进行讨论。仿真结果能够更加直观准确地区分电容的充放电过程及变化趋势,得出在不同情况下时间常数的测量方法。
To better understand the transient process, the paper introduces the basic principle for the simulation on the transient process of first-order resistor-capacitance(RC) circuit, simulates this process with Multisim software and based on fullcharge or full-discharge of the capacitance, discusses how to measure the time constant of a RC circuit. The simulation results show directly the charging and discharging processes and their tendencies, thereby contributing to measurement methods for time constant under various conditions.
