    • A limiter circuit includes a voltage rail having an input and an output, the input receiving an applied input voltage, a switching device in electrical communication with the voltage rail to selective control an electric current flowing through the output of the voltage rail, limiter capacitor in electrical communication with the input of the voltage rail and the switching device, wherein the limiter capacitor and the switching device are in parallel electrical communication between the input and an electrical ground, and a first resistor interposed between the limiter capacitor and the electrical ground, wherein an impedance of the resistor and the limiter capacitor define a time constant for the charging the limiter capacitor, and wherein the time constant of the limiter capacitor controls a voltage applied to the switching device and a current flowing through the output of the voltage rail.
    • 限幅器电路包括具有输入和输出的电压轨道,输入端接收施加的输入电压,与电压轨道电连通的开关装置,以选择性地控制流过电压轨的输出的电流,限制电容器 与电压轨和开关装置的输入端的电通信,其中限幅电容器和开关装置在输入和电接地之间并联电连接,以及插入在限制器电容器和电接地之间的第一电阻器,其中 电阻器和限幅电容器的阻抗限定了用于对限制电容器充电的时间常数,并且其中限制电容器的时间常数控制施加到开关器件的电压和流过电压轨的输出的电流。
