摘要： PURPOSE: A circuit for controlling a valve body is provided to control the solenoid valves of PWM(Pulse Width Modulation) and VFS(Variable Force Solenoid) by using one circuit. CONSTITUTION: A valve body control circuit(100) is composed of a driver circuit(101), a reverse surge protection circuit(103), and a feedback circuit. The driver circuit controls the main operation of the valve body control circuit. The driver circuit operates a PWM solenoid valve and a VFS solenoid valve. The driving circuit and the reverse surge protection circuit controls PWM solenoid valve. The valve body control circuit sets the period time, fullin time, holding frequency, and holding duty of the PWM solenoid valve. The valve body control circuit sets the softup time, softdown time, max current, frequency of the VFS solenoid valve.
