An air conditioner and a reverse-phase detection method thereof are provided. According to the air conditioner and the reverse-phase detection method thereof, it is possible to perform reverse-phase detection in real time by subtracting the voltage of one of two phases arbitrarily selected from the phases of an input three-phase alternating voltage from the voltage of the other phase and determining whether the input three-phase alternating voltage is reversed based on sign information of a voltage obtained by the subtraction. Thus, it is possible to prevent an air conditioner from malfunctioning due to a reversed input three-phase alternating voltage and to facilitate the management of an air conditioner. |
