摘要： An air conditioner (2). The air conditioner (2) comprises a power supply circuit (10), a power supply adjustment circuit (15), and a power supply control circuit (13). The power supply circuit (10) is coupled to an electric load (11) and is configured to convert an alternating-current power supply (VAC) into a plurality of direct-current power supplies, and the plurality of direct-current power supplies are used for supplying power to the electric load (11). The power supply adjustment circuit (15) is coupled to the power supply circuit (10). The power supply control circuit (13) is coupled to the power supply adjustment circuit (15) and the power supply circuit (10), and is configured to control the conduction angle of the power supply adjustment circuit (15) according to a power supply requirement for the electric load (11), so as to reduce the amplitude of the alternating current input into the power supply circuit (10).
