    Abstract: A motor driving device and an air conditioner including the same are disclosed. The motor driving device includes a rectifier to rectify input AC power, a boost converter for boosting the rectified power from the rectifier, a first capacitor to store a pulsating voltage from the boost converter, a first inverter for outputting, to a compressor motor, AC power transformed using a voltage across the first capacitor, a second capacitor to store the rectified power from the rectifier, a second inverter for outputting, 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 output the dropped voltage. In accordance with this configuration, the compressor motor and fan motor can be driven, using the same input AC power, even though the motor driving device uses a low-capacitance capacitor.

    Abstract: A power conversion apparatus includes a rectifier to rectify a voltage of an input alternating current (AC) power source and a voltage drop device to output a dropped voltage using the voltage from the rectifier, and the voltage drop device includes a transformer and a communication voltage output device provided at a secondary side of the transformer to output a first direct current (DC) voltage for operation of a communication device. The communication voltage output device includes a first resistor provided at the secondary side of the transformer to reduce an output change rate of the first DC voltage and first and second zener diodes connected between the first resistor and ground to limit an upper limit of the first DC voltage. Accordingly, it is possible to stably supply a voltage to a communication unit while reducing standby power.
