  "textContent": "This application discloses a charging module, a charging device, and a charging system. The charging module includes a three-phase rectifier module, a bus capacitor module, an inductor, and a controller. An input end of the three-phase rectifier module is electrically connected to an input power supply, and an output end of the three-phase rectifier module is electrically connected to an input end of the bus capacitor module. The bus capacitor module includes a first bus capacitor and a second bus capacitor. The first bus capacitor is connected between a first output end of a three-phase bridge arm and a midpoint of the three-phase bridge arm, and the second bus capacitor is electrically connected between a second output end of the three-phase bridge arm and the midpoint. The inductor is electrically connected to the midpoint of the three-phase bridge arm and a midpoint between the first bus capacitor and the second bus capacitor. The controller is configured to: obtain an input voltage and an input current of the charging module, and control a status of the three-phase rectifier module based on the input voltage and the input current. In this application, a power factor correction function can be implemented, and there is an effect of improving a bus ripple and an input current waveform in a working condition with a non-unity power factor.",
