1. A motor driving device comprising:

  • a rectifier to rectify input alternate current (AC) power;

    a boost converter to boost the rectified power from the rectifier, and to provide boosted power;

    a first capacitor to store voltage from the boost converter;

    a first inverter that includes a plurality of switching elements, the first inverter to provide, to a compressor motor, AC power transformed using a voltage across the first capacitor;

    a second capacitor to store voltage from the rectifier;

    a second inverter that includes a plurality of switching elements, the second inverter to provide, to a first fan motor, AC power transformed using a voltage across the second capacitor; and

    a voltage dropper to drop the voltage across the second capacitor, and to provide the dropped voltage.
