  "textContent": "Embodiments of this application provide a power system. An output terminal of a power supply or a DC-to-DC unit is cascaded to increase an output voltage, to reduce a current between the power supply or the DC-to-DC unit and a DC-to-AC unit, and resolve cost and loss problems of a cable from the power supply or the DC-to-DC unit to the DC-to-AC unit. In addition, according to the power system provided in embodiments of this application, a quantity of cables from the power supply or the DC-to-DC unit to the DC-to-AC unit may be further reduced by cascading an output terminal of the power supply or the DC-to-DC unit and cascading an input of the DC-to-AC unit, to reduce system costs. In addition, in the power system provided in embodiments of this application, the cascaded input and isolated output of the DC-to-AC unit can reduce a specification of a power conversion device. Therefore, problems of insufficient specifications and high costs of power conversion devices in the current industry are resolved. In addition, according to the power system provided in some embodiments, a problem of potential induced degradation (PID) caused by a negative voltage of a cell panel to ground during operation of the system may be further resolved.",
