Abstract
One or both of a duty for conducting a switch for intermittently applying a first voltage boosted from a booster to a direct-current link and the first voltage are controlled. When an alternating-current power output from an inverter is equal to or more than a second threshold less than a first threshold, an equivalent direct-current voltage is controlled to be higher than a peak value of a rectified voltage that is rectified by a converter and equal to or less than a first voltage; and when the alternating-current power has a first value more than the first threshold, the equivalent direct-current voltage is higher than the equivalent direct-current voltage when the alternating-current power has a second value more than the second threshold and less than the first threshold.
