[0002] During the working process of large-scale generator sets, it is necessary to monitor the working status of the generator. Various sensors, such as temperature sensors, vibration sensors, and some chips for signal processing, need to be used in the monitoring process. Stable low-voltage direct current. In the existing technology, these low-voltage direct currents are often converted from alternating current to direct current through existing power storage equipment or voltage conversion equipment, and then powered by voltage conversion. The battery is used for power supply. Although the power supply is stable, the battery needs Frequent charging is inconvenient to use, and although the power supply method using alternating current conversion can also achieve continuous power supply, the voltage of the alternating current of the mains or the alternating current output by the generator is generally high, which is likely to cause equipment damage; In the process, there are harmonic components in the excitation current. Generally speaking, these harmonics are useless and will be filtered, and because the harmonic components of the excitation current are relatively weak, they are not fully utilized in the prior art
