Abstract
A technology for suppressing a performance degradation of a solar battery caused by PID is provided. A conversion device includes a DC/DC converter and a control part. A solar battery is connected to an input end of the DC/DC converter. When direct-current power generated by the solar battery is converted and output, the DC/DC converter makes a potential of a negative electrode of the solar battery to be higher than a potential in a negative electrode of the output when the power input from the solar battery exceeds a prescribed value. The control part changes a voltage of the power output from the solar battery to detect a peak value of the power, and stops the operation of the DC/DC converter when the peak value is smaller than the prescribed value.
