  • Electronically commutated fan system
    Patent number: 10153721
    Abstract: An electronically commutated fan system includes an alternating-current-to-direct-current conversion unit, an inverter unit and a control unit. The alternating-current-to-direct-current conversion unit converts an alternating-current input power source into a first direct-current power source. The inverter unit is electrically connected between the alternating-current-to-direct-current conversion unit and a fan. The inverter unit converts the first direct-current power source into an alternating-current output power source and provides the alternating-current output power source to the fan to rotate. The control unit is electrically connected to the alternating-current-to-direct-current conversion unit and the inverter unit. The control unit controls the alternating-current-to-direct-current conversion unit and the inverter unit to adjust a rotational speed of the fan.
