    • The vehicle generator regulating apparatus includes a switching device operating to allow a field current to flow into a field coil of the vehicle generator from a vehicle battery when applied with a voltage signal, a drive circuit applying the voltage signal to the switching device when supplied with a control signal, and a control circuit supplying the control signal to the drive circuit when the output voltage is detected to be not above a predetermined voltage. The drive circuit includes a charge pump circuit stepping up a DC voltage supplied from the battery to generate the voltage signal by repeatedly performing a cycle of charging and discharging multiple capacitors in synchronization with an oscillation signal from an oscillator circuit. The drive circuit is configured to lower the frequency of the oscillation signal when the vehicle generator is in a low power output state.
    • 车辆发电机调节装置包括开关装置,其在施加电压信号时工作以允许励磁电流从车辆电池流入车辆发电机的励磁线圈;驱动电路,当施加电压信号时,将其提供给开关装置 控制信号以及当检测到输出电压不高于预定电压时将控制信号提供给驱动电路的控制电路。 驱动电路包括电荷泵电路,其加强从电池提供的直流电压,以通过与来自振荡器电路的振荡信号同步地重复执行对多个电容器充电和放电的周期来产生电压信号。 驱动电路被配置为当车辆发电机处于低功率输出状态时降低振荡信号的频率。
