[Problem] To provide a solenoid valve drive control device that can conserve energy and that can suppress noise generated by inrush current by way of eliminating inrush current to stray capacitance of the coil and accumulating energy in a coil. [Solution] A solenoid valve drive control device comprises: a blocking mode in which current to a solenoid 66 is blocked by a switching means 68 when the current flowing to the solenoid 66 detected by a current detecting means 78 reaches a prescribed set current value Ia after current supply to the solenoid 66 is started at time of a zero-cross by the switching means 68 by way of the control of a zero-cross timing generating means 72; and a holding mode that is set so that the current flowing into the solenoid 66 is equal to or greater than a prescribed holding current value Ib by sending a holding current to the solenoid 66 through a snubber circuit 70 during the interval until the time of the next zero crossing after the current supply to the solenoid 66 is blocked by the switching means 68. |
