PROBLEM TO BE SOLVED: To provide a power conversion device capable of quickly restoring a generated power, which comes from a power source that is restricted when a system voltage drops, to an output before restriction when the system voltage is restored.SOLUTION: In a power conversion device which outputs a generated power of a solar battery module 3 to an AC system 2, in a case where a voltage amplitude of the AC system 2 is smaller than a set value, an output current upper limit Ilimit of a power converter 11 for controlling generated power is lowered to suppress overcharging with a smoothing capacitor 12 while lowering an output current command value Idc, and when overcharging with the smoothing capacitor 12 is being suppressed, the output current command value Idcis maintained without being updated. |
