Abstract

A power conversion apparatus (and an air conditioner including the same) may include 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. The voltage drop device may include a transformer and a communication voltage output device provided at a secondary side of the transformer to output a direct current (DC) voltage for operation of a communication device. Accordingly, a voltage may be stably supplied to the communication device while reducing standby power.

Description

technical field

[0001] The present invention relates to a power conversion device and an air conditioner including the same, and more specifically, to a power conversion device capable of stably supplying power to a communication unit while reducing standby power, and an air conditioner including the same. Background technique

[0002] In order to create a comfortable indoor environment, the air conditioner spits out cold and warm air into the room, adjusts the indoor temperature and purifies the indoor air, thereby providing users with a more comfortable indoor environment. In general, an air conditioner includes: an indoor unit including a heat exchanger and installed indoors; an outdoor unit including a compressor, a heat exchanger, and the like, and supplying refrigerant to the indoor unit.

[0003] In addition, in order to communicate between the indoor unit and the outdoor unit, the indoor unit and the outdoor unit are respectively provided with communication units, an...
