    摘要： An electronically commutated fan system (100) includes an alternating-current-to-direct-current conversion unit (10), an inverter unit (20) and a control unit (30). The alternating-current-to-direct-current conversion unit (10) converts an alternating-current input power source (Viac) into a first direct-current power source (Vdcl). The inverter unit (20) is electrically connected between the alternating-current-to-direct-current conversion unit (10) and a fan (40). The inverter unit (20) converts the first direct-current power source (Vdcl) into an alternating-current output power source (Voac) and provides the alternating-current output power source (Voac) to the fan (40) to rotate. The control unit (30) is electrically connected to the alternating-current-to-direct-current conversion unit (10) and the inverter unit (20). The control unit (30) controls the alternating-current-to-direct-current conversion unit (10) and the inverter unit (20) to adjust a rotational speed of the fan (40). When the control unit (30) detects a power variation of the alternating-current input power source (Viac), the control unit (30) controls the rotational speed of the fan (40) to be maintained within a first error range (Rel).

    摘要： A fan system, which is driven by any of an AC power source and a DC power source, includes a fan motor, a voltage stabilizing module and a driving circuit connecting to the fan motor. The voltage stabilizing module includes an input end and a voltage conversion unit. The input end is coupled to an AC power source or a DC power source, and the voltage conversion unit is coupled to the input end for receiving the inputted DC or AC power. The voltage conversion unit keeps the DC or AC power at a working voltage level, which acts as a voltage signal to be transmitted to the driving circuit. The driving circuit receives the voltage signal and drives the fan motor to rotate accordingly.
