Abstract
The control device scans the output voltage of the first converter within a predetermined range to search for a maximum-efficiency voltage. At that time, the control device controls the output voltage of the first converter to the first voltage and acquires the output power of the first converter at that time as the first power, controls the output voltage of the first converter to the second voltage changed by the first change width from the first voltage and acquires the output power of the first converter at that time as the second power, and controls the output voltage of the first converter to the third voltage changed by the second change width from the second voltage in order, and sets the second change width to a value larger than the first change width when the second power is smaller than the first power.
