摘要：The present invention is to provide a magnet coil drive control device that canefficiently suppress conduction noise while reducing the capacitance of a capacitor. Acapacitor and an impedance element are arranged in series on the connecting lineconnecting the positive electrode line and the negative electrode line of a DC powersupply, the connecting line between the capacitor and the impedance element is

connected to one end of a magnet coil via a freewheeling diode, and the portion betweenthe freewheeling diode and the one end of the magnet coil is connected to the positiveelectrode line or the negative electrode line by a switching element. Conduction noisecaused by the driving current of the magnet coil can be suppressed by the impedanceelement, and the capacitance of the capacitor can be further reduced. Accordingly, themagnet coil drive control device can be made smaller in size.
