Abstract
According to one embodiment, when an effective value of an input current flowing into a booster circuit rises to a value greater than or equal to a second set value, boosting of the booster circuit is started and, after the start, when the effective value lowers to a value lower than a first set value lower than the second set value, boosting of the booster circuit is stopped. Then, if the three-phase AC source is in an unbalanced state, the first set value is set to a value lower than usual.
