Power converting apparatus, motor driving apparatus, and air conditioner

A power converting apparatus comprising:

• a reactor including a first terminal and a second terminal, the first terminal being connected to an alternating-current power supply;
• a bridge circuit connected to the second terminal of the reactor and including at least one or more switching elements, the bridge circuit converting an alternating-current voltage output from the alternating-current power supply into a direct-current voltage;
• a current detector detecting a current from the alternating-current power supply;
• a processor;
• and
• a memory storing a program which, when executed by the processor, performs processes of:
• controlling ON and OFF of the switching elements depending on a current value detected by the current detector, wherein
• the power converting apparatus includes two or more current thresholds for controlling ON and OFF of the switching elements,
• when an absolute value of the current value is equal to or larger than a first current threshold and equal to or smaller than a second current threshold, at least one or more of the switching elements is turned ON depending on a polarity of the current value, and
• when the absolute value of the current value is smaller than the first current threshold or larger than the second current threshold, at least one or more of the switching elements is turned OFF.
