ABSTRACT:
Disclosed herein is an electrorheological fluid damping control system. The suspension control system is comprised of a transformer and a rectifier circuit, which is electrically connected to a secondary winding of the transformer and is provided with capacitors. A capacitive load is electrically connected to output terminals of the rectifier circuit. When voltage to be applied across the capacitive load is cut off, electric charges stored in the capacitors and in a capacitive component of the capacitive load are discharged through a resistive component of the capacitive load. The capacitance of each capacitor is determined such that a discharge time constant of a circuit comprised of tile capacitors and the capacitive load is a predetermined value or less.
