Abstract

PURPOSE:To decrease hysteresis in a fine current region by decreasing the frequency of a waveform signal of a VCO oscillating part when a control part outputs a small voltage signal. CONSTITUTION:A control part 6, outputting a control voltage signal Vin, and a VCO oscillating part 7, outputting a triangular wave signal X, are respectively connected to a PWM modulation part 8, while a current signal from this PWM modulation part 8 is transmitted to a proportional solenoid valve 10 via a driver 9. The VCO oscillating part 7 decreases a frequency of its output signal, when low voltage of an output signal is generated from the control part 6, and increases the frequency when high voltage of the output signal is generated. In this way, when the frequency is decreased, the duty ratio generates no change, but the on-time of an on-off signal is lengthened.
