Abstract

The invention provides a power conversion apparatus and an air conditioner including the same. The power conversion apparatus provided by an embodiment of the invention 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.

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...
