<p>A method and system for driving an electromagnetic device are provided. The driving is carried out by energizing the electromagnetic device by applying a train of drive voltage pulses across an operating coil of the electromagnetic device so as to produce a sequence of transient current pulses therethrough. The drive voltage pulses have amplitudes significantly higher than the amplitude of a nominal operating voltage capable of operating said electromagnetic device in a continuous duty cycle operation regime. A duty cycle of the drive voltage pulses is chosen to assure that the current amplitude drops in the time interval between any two successive drive voltage pulses to a predetermined value that is significantly smaller than a maximum current amplitude of each current pulse.</p> |
