    • An engine-driven generator includes an internal combustion engine, a permanent magnet alternator and an AC to AC converter. The output frequency and voltage of the permanent magnet alternator are largely dependent on engine speed and the alternator load. The AC to AC converter converts the speed-dependent alternating potential developed by the alternator to another alternating potential whose frequency and voltage are largely independent of engine speed. Voltage regulation is provided by varying the engine speed in accordance with the load current. Frequency regulation is provided by frequency dividing the alternator output by an integer divisor that varies in accordance with engine speed. Additional voltage regulation is provided by deleting selected cycles of the alternator output current as needed to maintain the RMS output voltage within predetermined limits. A stepper motor coupled to the throttle of the internal combustion engine controls the speed of the engine in accordance with commands received from an electronic system control.
    • 发动机驱动的发电机包括内燃机,永磁式交流发电机和AC至AC转换器。 永磁发电机的输出频率和电压在很大程度上取决于发动机转速和交流发电机负载。 AC到AC转换器将由交流发电机开发的速度相关的交变电位转换为另一个交变电位,其频率和电压在很大程度上独立于发动机转速。 通过根据负载电流改变发动机转速来提供电压调节。 通过将交流发电机输出分频除以发动机转速变化的整数除数来提供频率调节。 通过根据需要删除交流发电机输出电流的选定周期来提供额外的电压调节,以将RMS输出电压维持在预定限度内。 耦合到内燃机的节气门的步进电机根据从电子系统控制接收的命令来控制发动机的速度。
