ABSTRACT:
A solenoid driving circuit for supplying an exciting current whose level suddenly increases at the beginning of the flow of the current has a voltage inducing circuit for providing a pulse-like current component which suddenly increases at the beginning of the flow of the exciting current, a unidirectional element for supplying the pulse-like current component to the solenoid and a voltage limiting element for limiting the level of the pulse-like current component and applying a d.c. power to the solenoid, whereby the solenoid is effectively supplied with sufficient energy for driving it at high speed.
