Using a permanent-magnetgenerator, the system delivers up to 400 amps of 28-volt DC electric power at low engine speed.
由于使用了永磁体发电机，CMPS系统可以在低功率速度下，提供最高400安培28伏特直流电源。

The terminal voltage of a common permanent-magnetgenerator varies with its rotating speed and load due to its constant permanent-magnet flux, which resulting in unstable quality of power supply.
普通永磁同步发电机由于励磁不可调，端电压随转速或负载变化而变化，影响了供电品质。

Meanwhile, the application of the permanentmagnet synchronous generator, which is simple in structure, high in efficiency and reliability, is limited by the difficulty to adjust its output voltage.
