Title:
ソレノイド駆動制御装置
Document Type and Number:
Japanese Patent JP4573008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solenoid drive control circuit capable of enabling a dither current necessary in the whole range of a solenoid exciting current to flow. SOLUTION: Detection signal of an exciting current is inputted into an arithmetic device 7 for obtaining an arithmetic output signal V0. The signal V0 and an instruction signal Vin which gives the target value of an exciting current are inputted into a comparator CP1, and a switching circuit 5 is turned ON or OFF corresponding to the output of the CP1, by which the exciting current of the solenoid 1 is controlled. A dither component generating signal Vb whose level changes with the output change of the comparator CP1 is inputted into the arithmetic device 7 to change the arithmetic output signal V0, and a dither current is superposed on an exciting current Is.
