Device for driving electric motors |
摘要 |
A device for driving electric motors includes a power stage with a variable duty-cycle coupled to a supply voltage. The power stage is suitable for driving an electric motor. The driving device includes a circuit that is capable of raising the value of the input voltage of the power stage above the induced counter electromotive voltage of the motor in certain periods of time and a control device capable of activating the circuit in reply to values of the induced counter electromotive voltage being greater than or comparable with the supply voltage.
