    摘要： A power converting apparatus (100) includes a rectifier (300) that converts alternating-current power from an alternating-current power supply (1) into direct-current power, a short-circuit unit (30) that short-circuits the alternating-current power supply (1) via a reactor (2), and a control unit (20) that controls a short-circuit operation of the short-circuit unit (30). The control unit (20) changes the number of times of the short-circuit operation during a half cycle of the alternating-current power supply (1) on the basis of a load condition and sets a period from a start to an end of the short-circuit operation during the half cycle of the alternating-current power supply (1) after the change of the number of times of the short-circuit operation to be different from a period from a start to an end of the short-circuit operation during the half cycle of the alternating-current power supply (1) before the change of the number of times of the short-circuit operation.
