Power converter, motor driver, and refrigeration cycle applied equipment

A power converter to be installed in a refrigeration cycle applied equipment, the power converter comprising:

• a rectifier configured to rectify a first alternating-current power supplied from an alternating-current power supply;
• a capacitor connected to output ends of the rectifier;
• an inverter connected across the capacitor, configured:
• to convert power output from the rectifier and the capacitor into a second alternating-current power;
• and
• to output the second alternating-current power to a load comprising a motor;
• and
• a controller configured:
• to control an operation of the inverter such that the second alternating-current power containing pulsation according to pulsation of power flowing into the capacitor from the rectifier is output from the inverter to the load;
• and
• to suppress current flowing to the capacitor,
• wherein
• in a state where predetermined power is received from the alternating-current power supply, a pulsation width of a pulsating current generated by the second alternating-current power is different depending on whether an operation of the refrigeration cycle applied equipment is a cooling operation or a heating operation.
