Abstract

Disclosed are an air conditioner and a control method thereof, which improve a power factor of the air conditioner by reducing a phase difference between a votlage and an electric current of a power source inputted to a compressor; and an air conditioner and a control method thereof, which enhance harmonic components by inputting an electric current of a sine wave to a compressor. In the air conditioner and a control method thereof, a power factor of three power source is compensated by phases and is inputted to a rectifier, thereby causing a voltage and an electri current of a power source applied to a compressor to become the same phase. Further, the electric current is inputted in a form of a sine wave in order to improve a power factor of the air conditioner and remove harmonic components of the power source ocurred. Moreover, an improvement in the power factor of the air conditioner and a removal of the harmonic components in the power source occurred enhance a performance and reliance of a product.
