The switched reluctance machine providing soft chopping in the output current controls the voltage across the phase winding. When the current through the phase winding in the generating mode reaches a first predetermined value, the voltage across the phase winding is reversed and as a result, the current through the phase winding decreases. When the phase winding current reaches a second value, the phase winding is shorted so that the current increases due to the positive back-EMF through the phase winding until the first predetermined value is again reached, at which time the voltage across the phase winding is again reversed.
