本例中的电路可以用来设定有良好控制的电压变化速率,一般可以表示为微分dV/dt(每秒电压的即时变化率)。用一只电位计可以改变灵敏度。dV/dt设为从1V/200ns至1V/3ms。输入电压区间可以从几伏至30V。用较高电压的晶体管可以提高电压上限。电路用一个缓慢而可控制的dV/dt为一只电容充电,以避免上电期间的大浪涌电流。用此电路也可以建立一个大的dV/dt,用于对其它电
The circuit in this example can be used to set a well-controlled rate of voltage change, which can generally be expressed as a differential dV / dt (instantaneous rate of change per second). With a potentiometer can change the sensitivity. dV / dt is set from 1V / 200ns to 1V / 3ms. The input voltage range can range from a few volts to 30V. With a higher voltage transistor can increase the voltage cap. The circuit charges a capacitor with a slow and controllable dV / dt to avoid large inrush currents during power-up. With this circuit it is also possible to create a large dV / dt for use with other power sources
