    摘要: A ventilation apparatus with a two-section feedback compensation control and a method for operating the same are disclosed. The ventilation apparatus includes a power conversion trait (10), a driven circuit (20), a DC motor (30), a current-sensing unit (40), a voltage compensation unit (60), and a control unit (50). The power conversion unit (10) receives and converts an AC power voltage (Vac) into a DC power voltage (Vo). The driven circuit (20) receives the DC power voltage (Vo) and outputs a driven voltage. The DC motor (30) is driven through the driven voltage. The current-sensing unit (40) senses an output current of the DC motor (30). The control unit (50) receives the output current to compare to a threshold current value, thus controlling the voltage compensation unit (60). Accordingly, the DC power voltage (Vo) is adjusted to adjust the speed of the DC motor (30).
