A power conditioner enables efficient and stable use of generated power during autonomous operation. During autonomous operation in which the power conditioner is disconnected from a power grid and allowed to independently supply power, each of DC-to-DC converters 11 individually switches between a constant DC link voltage mode in which an output voltage of the DC-to-DC converter 11 is controlled at a target voltage and an MPPT mode in which control is performed to maximize output power of a corresponding DC input power source, according to a change of an input voltage of a power converter 13, 16. |
