  "textContent": "A circuit for component voltage limitation and an apparatus for applying the same. A detection-and-control unit detects a parameter of a photovoltaic-cell string, and controls operation of a switch unit according to the parameter. In a case that the switch unit controls at least one photovoltaic cell connected to the switch unit to operate in a voltage-limited mode according to control of the detection-and-control unit, a voltage of the photovoltaic-cell string can be reduced. In a case that that the switch unit controls a photovoltaic cell operating in a voltage-limited mode to resume a normal output according to control of the detection-and-control unit, an output voltage of the photovoltaic-cell string can be increased. The rate of utilization on the direct voltage and the PVIR of DC/AC are improved for the photovoltaic system.",
