Abstract

PURPOSE:To enhance response characteristic of a solenoid of the high-speed drive circuit for the solenoid using a choke coil holding the voltage as low as it is by a method wherein the solenoid coil is connected to one side of a pair of switching circuits and a resistor to the other side, or the solenoid coil is connected to both circuits of the high-speed drive circuit for the solenoid using the choke coil. CONSTITUTION:The solenoid coil 3 and an additional resistor 4 are connected in series to one side of a pair of the switching circuits being made to ON and OFF alternately by transistors Tr1, Tr2 and inverters 1, 2 inserted in a signal input circuit thereof, the resistor 5 is connected to the other side, and both the circuits are connected in parallel to an electric power source line 7 being the choke coil 6 inserted in series in the electric power source side. Accordingly, rising-up characteristics of a current in the solenoid is made to be steep because of the constant-current characteristic of the choke coil and the current change-over characteristic of the transistors. Therefore performance characteristic of the solenoid can be improved holding the voltage at low as it is, and accordingly high-speed driving becomes possible.
