摘要：Avibration-reduction an driving circuit is applicable to a fan that operatesaccording to a current signal sent thereto, and is characterized in a current buffer unitconnected to a drive current supplied from a power source and having a relatively largemagnitude of change in current. The current buffer unit divides the original drive current
into multiple continuously changing drive currents that have a relatively small magnitudeof change in current, so that electric current supplied to the fan is regulated and outputfractionally to achieve the purpose of reducing the vibration of fan caused by a largemagnitude of change in current.
