Beschreibung
Zusammenfassung:	The invention relates to a blower control system comprising a driving motor for driving an air conditioner blower to rotate, a control device for controlling the driving motor on the basis of the position information of the air conditioner blower, and a rectifier module connected with an input three-phase power supply and the control device. The blower control system further comprises a bus voltage sampling device, an input three-phase current sampling device and a PWM (Pulse Width Modulation) device, wherein the bus voltage sampling device is used for acquiring a sampling bus voltage on a bus in the rectifier module; the input three-phase current sampling device is used for acquiring a sampling input three-phase current of the input three-phase power supply; and the PWM device is used for generating a PWM signal for controlling a power tube in the rectifier module on the basis of the sampling bus voltage and the sampling input three-phase current. The blower control system provided by the invention can stabi
