Power converting device

A power converting device comprising:

• a rectifier circuit that converts alternating-current power from an alternating-current power supply into direct-current power;
• a short-circuit unit that short-circuits the alternating-current power supply via a reactor connected between the alternating-current power supply and the rectifier circuit;
• and
• a control unit that controls an ON/OFF operation of the short-circuit unit during a half cycle of the alternating-current power supply, wherein
• the control unit includes:
• a driving-signal generating unit that generates a driving signal that is a switching pulse for controlling the ON/OFF operation of the short-circuit unit;
• and
• a pulse dividing unit that divides the driving signal into a plurality of switching pulses so that peak values of power supply current of the alternating-current power supply are within the range from an upper-limit threshold to a lower-limit threshold lower than the upper-limit threshold.
