Power converting apparatus, motor driving apparatus, and air conditioner

A power converting apparatus comprising:

• a bridge circuit including at least two legs each including switching elements connected in series, the bridge circuit converting an alternating-current voltage output from an alternating-current power supply into a direct-current voltage;
• a current detector detecting a current from the alternating-current power supply;
• a zero crossing detector detecting a voltage polarity of 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 outputs of the current detector and the zero crossing detector, wherein
• two switching elements in one leg are complementarily turned ON and OFF once or more times during a first control period between a time point prior to a power-supply voltage zero crossing by a predetermined period and a time point later than the power-supply voltage zero crossing by a predetermined period.
