Motor driving device and air conditioner including the same

摘要

A motor driving device (200) and an air conditioner (100) including the same are disclosed. The motor driving device (200) includes a rectifier (410) to rectify input alternating current (AC) power, a boost converter (420) to boost and to output the power rectified by the rectifier (410), and an inverter (220) including a plurality of switching devices and to output converted AC power to a motor (250) using a voltage from the boost converter (420). Accordingly, a voltage utilization ratio of a voltage input to an inverter in the motor driving device using a low-capacitance capacitor (C) is enhanced.
